ABSTRACT SUBMISSION IS NOW OPEN 

DEADLINE FOR SUBMISSIONS IS APRIL 1, 2019

The VISPA research centre at the University of Victoria is proud to host the Conference on Flavor Physics and CP Violation, FPCP 2019. The conference will be held on the campus of the University of Victoria from May 6-10, 2019.

The FPCP conference series has been held annually since 2002, when it was founded through a merger of the Heavy Flavor (HF) and B Physics and CP Violation (BPCP) series.

The format of the conference consists primarily of plenary sessions where invited experts review the progress in both theory and experiment on a range of topics including.

• CP violation in hadrons and leptons
• Rare decays of hadrons and leptons
• Heavy quark decays and CKM metrology
• Heavy non-qqbar mesons and pentaquarks
• Neutrino physics and PMNS metrology
• Flavor and the Higgs and Dark sectors
• The interplay between flavor and high-p_T physics at the LHC

There will also be opportunities for shorter talks and poster presentations.

16:15 Search for the forbidden decays $D^0\to hh’ll’$ and observation of $D^0\to K^-\pi^+e^+e^-$

Decay modes with two oppositely charged leptons of different flavor correspond to lepton flavor violating (LFV) decays and are essentially forbidden in the Standard Model (SM) because they can occur only through lepton mixing. Decay modes with two leptons of the same charge are lepton-number violating (LNV) decays and are forbidden in the SM. Hence, decays of the form $D^0 \to hh'll’$ provide sensitive tools to investigate new mediators or couplings in physics beyond the SM. In this talk, we report on a search for decays of the type $D^0\to hh'll’$ (with $h,h'=K/\pi$ and $l,l’=e/\mu$) using data taken by the BABAR experiment at the PEP-II $e^+e^-$ collider at the SLAC National Accelerator Laboratory. Upper limits on the branching fractions are improved by up to two orders of magnitude. We also report on the observation of the flavor-changing neutral current (FCNC) decay $D^0\to K^-\pi^+e^-e^+$, which is strongly suppressed in the SM because of the Glashow-Iliopoulos-Maiani (GIM) mechanism. We measure $\mathcal{B}(D^0\to K^-\pi^+e^-e^+) = (4.0\pm0.5)\times 10^{-6}$ in the di-lepton mass range $0.675< m(e^+e^-) < 0.875$ GeV$/c^{2}$, where the production of the intermediate state $\rho \to e^+e^-$ dominates, and set upper limits for decays outside this interval where long-distance effects are not expected to be significant.

16:30 Implications for New Physics in b->smumu transitions after recent measurements by Belle and LHCb

We present a Bayesian analysis of the implications for new physics in semileptonic b → s transitions after including new measurements of RK at LHCb and new determinations of RK∗ and RK∗+ at Belle. We perform global fits with 2, 4, and 8 input Wilson coefficients, plus one CKM nuisance parameter to take into account uncertainties that are not factorizable. We infer the 68% and 95.4% credibility regions of the marginalized posterior probability density for all scenarios and perform comparisons of models in pairs by calculating the Bayes factor given a common data set. We then proceed to analyzing a few well-known BSM models that can provide a high energy framework for the EFT analysis. These include the exchange of a heavy Z boson in models with heavy vector-like fermions and a scalar field, and a model with scalar leptoquarks. We provide predictions for the BSM couplings and expected mass values.

16:45 Combined explanation of the B-anomalies.

There are four models of tree-level new physics (NP) that can potentially simultaneously explain the $b \to s \mu^+\mu^-$ and $b \to c \ell^- {\bar\nu}$ anomalies. They are the S3, U3, and U1 leptoquarks, and a triplet of standard-model-like vector bosons (VBs). In this talk, I describe an analysis of these models with general couplings. We find that, even in this most general case, $S_3$ and $U_3$ are excluded. For the U1 model, I discuss the importance of the constraints from lepton- flavor-violating processes. As for the VB model, it is shown to be excluded by the LHC bounds on high-mass resonant dimuon pairs. This conclusion is reached without any assumptions about the NP couplings.

17:00 Prospects for $\tau$ lepton physics at Belle II

The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run and main operation of SuperKEKB has started in March 2019. Belle II has a broad $\tau$ physics program, in particular in searches for lepton flavor and lepton number violations (LFV and LNV), benefiting from the large cross section of the pairwise $\tau$ lepton production in $e^+ e^-$ collisions. We expect that after 5 years of data taking, Belle II will be able to reduce the upper limits on LF and LN violating $\tau$ decays by an order of magnitude. Any experimental observation of LFV or LNV in $\tau$ decays constitutes an unambiguous sign of physics beyond the Standard Model, offering the opportunity to probe the underlying New Physics. In this talk we will review the $\tau$ lepton physics program of Belle II.

17:15 Measurement of hadronic cross sections with the BABAR detector

A program of measuring the light hadrons production in exclusive $e^+e^- \to$ hadrons processes is in place at BABAR with the aim to improve the calculation of the hadronic contribution to the muon $g-2$. We present the most recent results obtained by using the full data set of about 470 fb${^-1}$ collected by the BABAR experiment at the PEP-II $e^+e^-$ collider at a center-of-mass energy of about 10.6 GeV. In particular, we report the results on the channels $e^+e^- \to \pi^+\pi^-\pi^0\pi^0\pi^0$, e^+e^- \to \pi^+\pi^-\pi^0\pi^0\eta$, and $e^+e^- \to \pi^+\pi^-\eta$. These final states are studied in a wide mass range, from threshold production up to 4 GeV/$c^2$.

17:30 Measurement of the CKM angle $\gamma$ with Belle II

The CKM angle $\gamma$ is the least well known of the angles of the unitarity triangle and the only one that is accessible with tree-level decays in a theoretically clean way. The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The accelerator has already successfully completed the first phase of commissioning with the first electron positron collisions in Belle II recorded in 2018. The design luminosity of SuperKEKB is $8 \times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than the Belle experiment. The key method to measure $\gamma$ is through the interference between $B^+\to D^0 K^+$ and $B^+ \to \bar D^0 K^+$ decays which occurs if the final state of the charm-meson decay is accessible to both the $D^0$ and $\bar D^0$ mesons. To achieve the best sensitivity, a large variety of D and B decay modes is required, which is possible at Belle II experiment as almost any final state can be reconstructed including those with photons. With the ultimate Belle II data sample of 50 ab$^-1$, a determination of $\gamma$ with a precision of 1 degree or better is foreseen. This talk will explain the details of the planned measurement at Belle II and include results related to these measurements obtained with the data already collected.

17:45 Early physics prospects for radiative and electroweak penguin decays at Belle II

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run and the main operation of SuperKEKB has started in March 2019. Recent measurements of B decays proceeding through a flavor changing neutral current transition such as $b\to s$ transitions have shown deviations from the Standard Model (SM) prediction. These decays are forbidden at tree-level in the SM and can only occur via suppressed loop level diagrams. Rare decays of B mesons are thus an ideal probe for phenomena beyond the SM, since contributions from new particles can affect the decays at the same level as SM particles. In this presentation we will review the prospects for these decays at Belle II: Early physics goals of the Belle II physics program are to rediscover these rare decays. Especially radiative $b\to s \gamma$ decays can be measured on a small dataset and in the near future Belle II can provide independent tests of anomalies in $b\to s\ell \ell$ decays. Ultimately, the clean Belle II environment will allow to study modes with large missing energy such as $B\to K^\ast \nu \bar\nu$.

16:15 New Physics in $b\to c \tau \nu$: Impact of Polarisation Observables and $B_c \to \tau \nu$

In this talk I review the status of new physics in $b\to c \tau \nu$ transitions in the EFT framework of dimension-six operators. The fit results, including the recent measurement of $F_L(D^*)$, are presented for all one- and two-dimensional scenarios resulting from the tree level exchange of a single new particle. Particular emphasis is put on the constraint from the $B_c \to \tau \nu$ decay rate. I introduce a sum rule for the branching ratios of $B\to D \tau \nu$, $B\to D^* \tau \nu$ and $\Lambda_b\to \Lambda_c \tau \nu$ which holds for any NP contribution to the Wilson coefficients and predicts an enhancement of the latter decay w.r.t. the Standard Model. I discuss correlations between the polarisation observables in $B\to D \tau \nu$, $B\to D^* \tau \nu$ and their model-discriminating prospects. The talk is based on the results published in https://arxiv.org/abs/1811.09603.

16:30 Production of Lambda_b baryon and B0s mesons at LHCb

Heavy hadron production is well-suited as a benchmark process for understanding QCD. While b-quark production properties can be estimated within perturbative QCD, the subsequent fragmentation into a b hadron is a non-perturbative process and cannot be calculated from the first principles. Our understanding of fragmentation functions and fractions thus relies solely on experimental input. Recently, LHCb have taken a closer look at the properties of Lambda_b baryon and B_s meson production. The new results demonstrate that b-quark fragmentation clearly depends on the kinematics of the hadrons produced, and shed welcome light on B_s production.

16:45 Observation of several sources of CP violation in B+ -> pi+pi+pi- decays

Very large CP asymmetries in decays of B mesons to final states containing three charged particles have been observed and attracted much interest. We present new results from a Dalitz plot analysis of B->3pi using a data sample corresponding to an integrated luminosity of 3 fb-1 of pp collisions recorded by the LHCb detector. Significant CP violation from different sources (S-wave, D-wave,S-P wave interference etc.) are established and may shed new light on understanding the underlying dynamics for CP violation in hadronic B decays.

17:00 First look at time dependent CP violation using early Belle II data

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run, achieved a peak luminosity of $5.5\times 10^{33}$ cm$^{-2}$s$^{-1}$, and Belle II has recorded a data sample of about 0.5 fb$^{-1}$. Main operation of SuperKEKB has started in March 2019. This early data set is used to establish the performance of the detector in terms of reconstruction efficiency of final states of interest for the measurement of time dependent CP violation, such as $J/\psi K^{(*)0}$, $\eta' K_s$, and $\phi K_s$. A first assessment of the B flavor tagging capabilities of the experiment will be given, along with estimates of the Belle II sensitivity to the CKM angles $\phi_1/\beta$ and $\phi_2/\alpha$ and to potential New Physics contributions in penguin amplitudes dominated decays and in $b\to s\gamma$ transitions.

17:15 Renormalization Effects on Electric Dipole Moments in Electroweakly Interacting Massive Particle Models

We study the renormalization effects on electric dipole moments in the models with new electroweakly interacting massive fermions. The electric dipole moments are generated by the effective operators which arise from integrating out heavy particles at some scale in the models. We give the renormalization group equation for the Wilson coefficients of the effective operators from the scale where the operators are generated to the electroweak scale. Our numerical studies focus on the electric dipole moments in the mini-split supersymmetric scenario and the electroweakly interacting massive particle dark matter scenario. It turns out that the renormalization effects can give an enhancement factor being of the order of O(10)% in the mini-split scenario and being more than two in the minimal dark matter model.

Associated production of vector boson with quarkonia is a key observable for understanding the quarkonium production mechanisms, including the separation of single and double parton scattering components.

In addition, recent results on heavy flavour production measurements are reported in the Bu and Bc systems.

At present, there are discrepancies with the predictions of the SM in ${\bar B} \to D^{(*)} \ell^- {\bar\nu}$ decays, suggesting the presence of new physics (NP) in $b \to c \tau^- {\bar\nu}$. Various NP models have been proposed to explain the data. In this talk, I discuss how the measurement of CP-violating observables in ${\bar B} \to D^* \ell^- {\bar\nu}$ can be used to differentiate the NP scenarios.

14:10 Test of CP violation and measurement of mixing in charm at LHCb

The copious number of D0 decays collected by the LHCb experiment during 2011-2018 enables tests for CP violation in charm decays and measurements of the D0 mixing parameters with unprecedented precision. To take maximum advantage of these statistics, control of systematic uncertainties is becoming more and more important, and will be even more so after the planned upgrades of the LHCb detector. We present the latest LHCb measurements of mixing and indirect CP violation in the decay of D0 mesons.

14:25 Time-dependent CPV in Bs decays at LHCb

Time-dependent CP-violation measurements of beauty mesons allow the determination of the mixing-induced CP-violating phases phi_s and beta. The measurement of the phase phi_s in the Bs-Bsbar system is one of the key goals of the LHCb experiment due to the sensitivity to physics beyond the Standard Model (BSM). The CP-violating phase is of interest in penguin dominated b->s transitions, in addition to that of tree-level decays, which test the flavour changing neutral current interaction describing B mixing. Both are sensitive to BSM phases and provide valuable tests and constraints. We present new results of time-dependent CP violation using data collected at LHCb between 2011 and 2016.

CP violations have been established in beauty mesons basically in two-body states, but so far not for charm mesons. Yet it is crucial to measure CP asymmetries in many-body final states -- including for beauty & charm baryons! Non-perturbative QCD gives large impact. [Of course, these results do not help us to understand the matter vs. anti-matter in our Universe.]

14:55 Impacts of QED radiative corrections on R(D) ratios

A recent paper (Phys. Rev. Lett. 120, 261804) presented a new evaluation of radiative corrections in the decay channels involved in the ratios $\mathcal{R}(D^+)$ and $\mathcal{R}(D^0)$, which could explain part of the discrepancy between measurements and SM predictions. Using simulated events we quantify the difference between the results in this paper and Photos, which is used to simulate radiative corrections both by LHCb and the B-factories. In addition, we designed a simplified analysis in LHCb to quantify the effect of neglecting radiative corrections on measurements of $\mathcal{R}(D^+)$ and $\mathcal{R}(D^0)$. A paper on this analysis will be submitted to a journal shortly.

The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run, achieved a peak luminosity of $5.5\times 10^{33}$ cm$^{-2}$s$^{-1}$, and Belle II has recorded a data sample of about 0.5 fb$^{-1}$. Main operation of SuperKEKB has started in March 2019. In this presentation we show first results from studying missing energy signatures, such as leptonic and semileptonic B meson decays based on early Belle II data. We report first studies on re-measuring important standard candle processes, such as the abundant inclusive $B\to X\ell\nu$ and $B\to D^*\ell\nu$ decays, and evaluate the performance of machine learning based tagging algorithms. Furthermore, we will also present an overview of the semileptonic B decays that will be measured in the upcoming years at Belle II and discuss prospects for important B-anomalies like R(D) and R(D*), as well as other tests of lepton flavor universality.

We use this dataset to characterize the performance of the detector regarding the tracking of charged particles, the reconstruction of known resonances, and the capability of identifying displaced decay vertices. To assess the B Physics capabilities of the experiment, one of the first benchmarks consists in the measurement of the lifetime of B mesons and of the $B^0-\bar B^0$ mixing frequency. We present the first results, based on samples of B mesons that decay to hadronic and semileptonic final states.

17:00 Results from the CUORE experiment

The Cryogenic Underground Observatory for Rare Events (CUORE) is the first bolometric experiment searching for neutrinoless double beta decay (0νββ) that has been able to reach the one-ton scale. The detector consists of an array of 988 TeO$_2$ crystals arranged in a compact cylindrical structure of 19 towers. The construction of the experiment was completed in August 2016 with the installation of all towers in the cryostat. Following a cooldown, diagnostic, and optimization campaign, routine data-taking began in spring 2017. In this talk, we present the 0νββ results of CUORE from examining a total TeO$_2$ exposure of 86.3 kg∙yr, characterized by an average energy resolution of 7.7 keV FWHM and a background in the region of interest of 0.014 counts/(keV∙kg∙yr). In this physics run, CUORE placed the current best lower limit on the $^{130}$Te 0νββ half-life of > 1.3 × 10$^{25}$ yr (90% C.L.). We then discuss the additional improvements in the detector performance achieved in 2018, the latest evaluation of the CUORE background budget, and we finally present the most precise measurement of the $^{130}$Te 2νββ half-life to date.

17:15 Meson-Hybrid Mixing in Vector and Axial Vector Charmonium

We investigate mixing between conventional mesons and hybrid mesons in vector and axial vector charmonium using the QCD sum-rules formalism. We compute meson-hybrid cross correlators within the operator product expansion, taking into account condensate contributions up to and including those of dimension-six as well as composite operator renormalization-induced diagrams. Using measured masses of charmonium states as input, we probe known resonances for nonzero coupling to both conventional meson and hybrid meson currents, a signal for meson-hybrid mixing.

17:30 Exotic Quarkonium Physics Prospects at Belle II

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at KEK in Tsukuba, Japan. It aims to record a factor of 50 times more data than its predecessor. The experiment completed a commissioning run in 2018, and began full operation in early 2019. Belle II is uniquely capable of studying the so-called "XYZ" particles: heavy exotic hadrons consisting of more than three quarks. First discovered by Belle, these now number in the dozens, and represent the emergence of a new category within quantum chromodynamics. This talk will present the prospects of Belle II to explore both exotic and conventional quarkonium physics.

17:45 Sensitivity to the X(3872) total width at the Belle II experiment

The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the B factory facility at the Japanese KEK laboratory. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July 2018, the machine has completed a commissioning run and main operation of SuperKEKB has started in March 2019. The X(3872) is an exotic hadron candidate and studying the X(3872) partial widths is a good probe for the internal structure of this hadronic state. However, in order to derive partial widths, a measurement of its total width is needed. The large Belle II data set will provide an ideal environment to measure the X(3872) total width since it will be possible to use the $X(3872)\to D^0 \bar{D}^0 \pi^0$ decay$, which has a better mass resolution than $X(3872)\to J/\psi\pi^+\pi^-$ used in earlier work. In this presentation, we will give an overview of the analysis and the expected sensitivity to the X(3872) total width

17:00 Dark Sector Physics with Belle II

The Belle II experiment is a substantial upgrade of the Belle detector and will operate at the SuperKEKB energy-asymmetric $e^+ e^-$ collider. The design luminosity of the machine is $8\times 10^{35}$ cm$^{-2}$s$^{-1}$ and the Belle II experiment aims to record 50 ab$^{-1}$ of data, a factor of 50 more than its predecessor. From February to July of this year, the machine has completed a commissioning run, achieved a peak luminosity of $5.5\times 10^{33}$ cm$^{-2}$s$^{-1}$, and Belle II has recorded a data sample of about 0.5 fb$^{-1}$. Already this data set with specifically designed triggers offers the possibility to search for a large variety of dark sector particles in the GeV mass range complementary to LHC and dedicated low energy experiments but these searches will benefit from more data soon to be accumulated. This talk will review the state of the dark sector searches at Belle II with a focus on the discovery potential of the early data.

17:15 Electric Dipole Moments From Dark Sectors

We examine the sensitivity of electric dipole moments (EDMs) as precision observables for new $CP$-violating physics in a dark sector. Assuming that the dominant mediation channel is via one or more of the vector, Higgs or neutrino portals, we examine the leading EDM contributions. The dominant contributions arise at two-loop order, and EDMs can provide sensitivity to portal couplings that is complementary to direct probes at the intensity frontier or high energy colliders. In particular, we identify a significant two-loop contribution to the electron EDM, mediated through the singlet (Higgs plus neutrino) portal, for which EDMs already provide new and complementary sensitivity in the regime of large singlet neutrino masses.

17:30 Higgs boson couplings to quarks at the ATLAS experiment

Testing the couplings of the Higgs boson to quarks is important to understand the origin of quark masses. The talk presents cross section measurements in Higgs boson decays to two b quarks, as well as a search for Higgs boson decays to two c quarks. It also presents measurements of Higgs boson production in association with a ttbar pair using Higgs boson decays to bbbar pairs, to two Z bosons, to other multi-lepton final states, and to a pair of photons. All analyses are based on pp collision data collected at 13 TeV.

17:45 ATLAS measurements of CP Violation and Rare decays in Beauty mesons

The ATLAS experiment has performed accurate measurements of mixing and CP violation in the neutral B mesons, and also of rare processes happening in electroweak FCNC-suppressed neutral B-mesons decays. This talk will focus on the latest results from ATLAS, such as rare processes: B^0_s -> mu mu and B^0 -> mu mu; and CPV in Bs to Jpsi Phi.
