        Sensitivity of Neutron Beta Decay Observables to BSM Interactions 35m
        The extraction of Vud from the lifetime of the neutron and it's dependence on radiative, recoil and weak magnetism corrections will be reviewed. In addition, the sensitivity of neutron asymmetries and the lifetime of the free neutron to contributions of BSM interactions of order 10^-4 will presented. Finally, new results on the sensitivity of bound state beta decay observables to contributions of BSM interactions will be shown.

        The neutron lifetime 35m
        The free neutron decays to a proton, electron, and antineutrino with a lifetime of about 15 minutes. Neutron decay is the prototype for nuclear beta decay and other semileptonic weak decays. The value of the neutron lifetime, along with neutron decay correlation parameters, provides direct access to the vector and axial vector weak couplings of the nucleon and the CKM matrix element Vud and can search for hints of new physics beyond the Standard Model. The neutron lifetime is a key ingredient in theoretical calculations of primordial element abundances from Big Bang nucleosynthesis. Two main methods, the beam method and the ultracold neutron bottle method, have approached the 10^-3 precision level in recent years, but unfortunately these two methods currently disagree by more than 8 seconds (almost 4 standard deviations). I will discuss the motivation and physics of the neutron lifetime and briefly review past experiments and future plans.

        New physics searches in leptonic decays of B mesons 20m
        Leptonic decays of B mesons are well understood in the Standard Model (SM) and highly suppressed due to helicity conservation. The leptonic branching fraction measurements can provide stringent constraints on New Physics, where particles or forces outside of the SM can suppress or enhance the decay rate. Experimentally, due to the small branching fractions, it is a challenge to measure the decay rates and this requires intense B-meson beams and sophisticated analysis techniques for signal selection. We review the recent results from B factories where the clean e+e- environment and excellent detector performances allow us to study B-meson decays into a charged lepton and a neutrino, as well as their implications for New Physics searches.

The extrapolations to the continuum limit and to the physical point as well as other sources of systematic uncertainties are analysed. A comparison of results from simulations with two and four flavour dynamical quarks will be presented.

        Review of QCD sum rule results (comparison with LQCD) 25m
        In this talk I will present the lattice averages for the decay constants of the D- and the B-meson performed by the Flavor Lattice Averaging Group (FLAG) and compare them with the corresponding updated predictions from Borel QCD Sum Rules for heavy-light currents. An excellent agreement is obtained in the charm sector, while some tension can be observed in the bottom sector. Furthermore, available lattice and QCD sum rule calculations of the decay constants of the vector D*- and B*-mesons will be compared. Again some tension in the bottom sector can be observed.

        Inclusion of isospin breaking effects in lattice simulations 30m
        Isospin symmetry is explicitly broken in the Standard Model by the non-zero differences of mass and electric charge between the up and down quarks. Both of these corrections are expected to have a comparable size of the order of one percent relatively to hadronic energies. Although these contributions are small, they play a crucial role in hadronic and nuclear physics. We explain how to properly define QCD and QED on a finite and discrete space-time so that isospin corrections to hadronic observables can be computed ab-initio. We then consider the different approaches to compute lattice correlation functions of QCD and QED observables. Finally we summarise the actual lattice computations which include isospin breaking effects.

        Vcb experimental review 20m
        The most precise measurements of Vcb today come from semileptonic B decays at the B-factories BaBar and Belle. We present an overview of their measurements with a focus on the most recent results. Different approaches are used to determine Vcb: inclusive and exclusive measurements; tagged and untagged analyses or global fits. We also give a summary on how the most recent measurements affect the discrepancy between inclusive and exclusive Vcb results.

        We present the results for the normalization of the relevant form factor mediating the semileptonic B-->Dlnu and Bs-->Ds lnu decays in the Standard Model, as obtained by using the maximally twisted mass QCD on the lattice with Nf=2 dynamical light quarks, and with the fully propagating heavy quark. Furthermore, the form factors needed for description of these decays in a generic scenarios of physics beyond the Standard Model near zero recoil are also presented. Preliminary results for F(1), needed to normalize B-->D* lnu and Bs-->Ds* lnu decays, are also presented in this talk.

        Vcb from B--> D^* l nu on the lattice 20m
        I will discuss the recent results for the B->D*lv and B->Dlv semileptonic form factors and the determination of |V_cb| from the Fermilab/MILC collaborations. These lattice calculations use an improved staggered action for the light quarks and the Fermilab action for the charm and bottom quarks; the calculation uses the MILC (asqtad) ensembles with three flavors of sea quarks and five lattice spacings. The zero-recoil B->D*lv calculation is an update of their 2008 result, with higher statistics, finer lattice spacings, and lighter light quark masses. The error is now commensurate with the experimental error. The B->Dlv calculation determines the form factors at non-zero recoil and a combined fit with the experimental data over the full kinematic range is performed to determine |V_cb|. Preliminary results for this channel will be presented.

        Exclusive semileptonic B decays to high-mass charm hadrons 19m
        The experimental knowledge of semileptonic B decays to a D or D* meson with one or more pions is limited. These limitations are relevant to two experimental puzzles: the tension between the values of Vcb determined from inclusive and exclusive semileptonic decays, and the gap between the sum of the exclusive semileptonic B decays to charm and the inclusive b -> c l nu rate. The full BABAR data set is used to improve the precision on decays involving D(*) pi l nu and to search for decays of the type D(*) pi pi l nu. Fully-reconstructed hadronic B decays are used to tag events and provide good resolution on the discriminant variable U = E_{miss}-P_{miss}. A simultaneous fit to charged and neutral B decays to D(n\pi) and D*(n\pi) decays is used to extract relative branching fractions. In addition to studying these high mass charm final states, the data are used to determine a precise measurement of the ratio of branching fractions for B -> D l nu / B -> D* l nu.

        Charm and bottom masses from QCD sum rules: new results and proper treatment of uncertainties 16m
        We briefly review recent charm and bottom mass determinations based on perturbative QCD. We give new results on MSbar charm mass using as input lattice moments of the pseudoscalar current correlator. We also give an update on the MSbar bottom mass based on e+e- data, which quantifies the uncertainties from energies where no measurements exist and uses latest theory input. Both analyses are based on a careful analysis of the theoretical uncertainties from the truncation of the perturbative series and avoid the accidental cancellation of scale variations contained in some of the previous sum rule analyses.

        DCPV in charmless B decays at Belle 20m
        We report preliminary measurements of the Branching Ratio (BR) for the charmless rare decays B0 -> pi0 pi0, B0 -> eta’ K*(892)0 and B+ -> Kbar*0 K*+. We also report the preliminary results for A_CP for B0 -> eta’ K*0 and the longitudinal fraction for B+ -> Kbar^*0 K*+. Previous Belle measurements of the BR for B^0 -> pi^0 pi^0 are significantly larger than theoretical expectations and employed approximately one third of the full data set. The mode B -> eta’ K*(892)^0 is sensitive to a potentially large flavor-singlet contribution. Previous studies provided evidence for its existence at the 4-sigma level. The decay B0 -> K* K* proceeds via a b-> d penguin process and is sensitive to New Physics contributions. All three measurements employ the full data set of 711fb-1 available at Belle.

        We present the results of a new search for B-meson decays to omega omega, and omega phi. These modes, yet unseen, are related to B -> phi K* decays via an SU(3) rotation. Their study can therefore provide information regarding the unexpectedly small value of the longitudinal spin component (f_L) measured in B -> phi K* decays. We also report the first Dalitz-plot analysis of charged B mesons decays to Ks pi+ pi0. We observe an excess of signal events and measure the branching fractions and CP asymmetries, for the different resonant decay modes and inclusively. The two analyses are performed using the full BABAR dataset of 471 million BBbar events collected at the Upsilon_(4S) resonance.

        DCPV in charmless B decays at LHCb 20m
        Charmless B hadrons decays offer rich opportunities to test the Standard Model. For example, CP violation in charmless charged two-body and three-body B decays provides ways to measure the CKM angle gamma and to search for New Physics. Also, vector-vector final states provide additional interesting observables. Here, we present the latest LHCb results on hadronic charmless B decays putting emphasis on the direct CP violation measurements

        Impact of D-mixing and CPV in D decays on the determination of gamma/phi3 25m
        The datasets that the LHCb and Belle II experiments are expected to collect in the coming years will allow a 1-degree precision measurement of the angle gamma (phi3) using Bch->D(*)0K(*) decays. To reach this goal a number of subleading effects must be taken into account. We disuss these corrections, including the impact of D-Dbar mixing and possible CPV in D decays.

        World average and experimental overview of gamma/phi3 25m
        Determination of the parameters of the Cabibbo-Kobayashi-Maskawa (CKM) matrix are important as checks on the consistency of the Standard Model, and as ways to search for new physics. Among the angles of the CKM unitarity triangle, gamma is the least-well constrained by direct measurements. In this talk, we report the determination of the angle gamma through the combination of measurements performed by the Babar, Belle and LHCb experiments involving B to DK, D*K and DK* decays.

The experimental information is combined following the HFAG prescriptions to account for statistical and systematic correlations, and the dependence of experimental results from external parameters for which updated information exists. The 2012 HFAG tau branching fraction fit has been updated with new measurements and external parameters since then.

        Some recent experimental results on measurements of branching fraction of leptonic D(s)+ decays and semileptonic D decays, which were measured at the BaBar, Belle, BESIII and CLEO-c experiments in the last several years, are reviewed. The decay constants of D(s)+ mesons as well as form factors of D semileptonic decays are also briefly reviewed. In addition, the extraction of |V_cd| and |V_cs| based on these measurements are discussed.

In addition one can compare the shape of the form factors from lattice QCD and experiment, and use the full experimental q^2 range (partial decay rates in q^2 bins) to determine the CKM matrix elements.

The heavy quark is treated in non-perturbative Heavy Quark Effective Theory (HQET). We discuss how to extract physical information from our raw measurement data and present first results in the form of a data point for the form factor at $q^2=21.23\,\textnormal{GeV}^2$ extrapolated to the continuum. We also address the inclusion of next-to-leading order terms in HQET and chiral extrapolation, which have yet to be performed.

        B--> D** l nu - puzzle 1/2 vs 3/2 20m
        Understanding the composition of final states in B --> Xc l nu could help to get a feedback on the persisting disagreement between exclusive and inclusive determinations of Vcb. In particular the series of orbital excitations D** and radial excitations (D', D*') has received a lot of attention; a misinterpretation as a scalar state of the (D' --> D pi) spectrum tail could have induced an experimental overestimate of the broad states contribution to the total B --> Xc l nu width with respect to theoretical expectations, all of them made however in the infinite mass limit: it is the so-called 1/2 vs 3/2 puzzle. We will describe first attempts to measure on the lattice form factors of B --> D** l nu at realistic quark masses. Cleaner processes, like hadronic decays B --> D** pi and semileptonic decays Bs --> Ds** l nu in the strange sector have recently been examined by phenomenologists, putting new interesting ideas on those issues with, again, the need of lattice inputs.

        Measurement of the D -> pi- e+ nu partial branching fraction: form factor and implications for Vub 20m
        Measurement of the D -> pi- e+ nu partial branching fraction, form factor and implications for Vub. Precision measurements of the D -> pi e+ nu form factor could shed new light on the persistent difference between inclusive and exclusive measurements of Vub. We report the measurement of the partial branching fraction of D -> pi e+ nu in bins of the four-momentum transfer squared of the D to pi system using 347.2 /fb of integrated luminosity of the BaBar data. The D -> pi form factor is extracted with fits to the unfolded partial branching fraction using pole or generalized expansions and the value at zero recoil is determined. These form factors are compared to the current world average, the available lattice predictions, and interpreted with the expectation of a single dominant pole term. The measured form factor is then combined with previous BaBar B -> pi l nu information to determine a value of Vub.

In a new physics scenario, one possibility to accomodate these two experimental facts consists in considering an additional tensor operator in the effective weak hamiltonian. We study the effects of such an operator in a set of observables, in semileptonic $B \to D^{(*)}$ modes as well as in semileptonic $B$ and $B_s$ decays to excited positive parity charmed mesons.

        The observed discrepancy between the experimental results and the Standard Model prediction for the ratios of the branching fractions of the decays B-> D(*) tau nu and B-> D(*) mu nu came as a surprise and lead to a discussion of testing New Physics through these modes. We discuss the possibilities for observing the New Physics effects by examining the q^2 and the angular distributions of the decay products. In particular we find new observables that could be accessible experimentally and that can be sensitive to the effects of physics beyond the Standard Model and be useful for discriminating various new physics scenarios.

        Rare K decays (theory) 20m
        Rare K decays belong to the cleanest observables in flavor physics and are highly sensitive to heavy new particles. I review the status of the standard model predictions and also shortly discuss the new-physics expectations.

        K --> pi nu nu at KOTO 20m
        The KOTO experiment aims to discover the rare decay KL->pi0nunu at the J-PARC 30 GeV proton synchrotron. This mode violates the CP symmetry directly and is highly suppressed in the Standard Model. Thus the mode is sensitive to new physics beyond the SM, in particular the physics related to CP violation. KOTO is an upgrade of the E391a experiment at KEK, and includes a new CsI Calorimeter, DAQ system and high intensity beam. KOTO performed engineering and commissioning runs to study the detector performance until early 2013, and finally started the first physics run in May 2013. Although data taking time was terminated after 100 hours due to an accident, the experiment achieved nearly the same sensitivity as the KEK E391a experiment, which holds the current best limit on this decay. In this contribution, the preliminary result of the first physics run will be reported.

        K --> pi nu nu at NA62 20m
        The main goal of the NA62 experiment at the CERN SPS is to measure the branching ratio of the ultra-rare K+ -> pi+ nu unbar decay with 10% accuracy. The NA62 strategy foresees the collection of ~ 100 K+ -> pi+ nu unbar decays in two years of data taking, keeping the background at the level of 10%. This measurement can provide stringent tests of SM predictions, also offering a complementary approach, with respect to the LHC high energy frontier, to probe new physics at short distances, corresponding to energy scales up to ~100 TeV. Part of the experimental apparatus has been commissioned during a technical run in 2012. The physics prospects and the status of the experiment will be reviewed in view of the first physics run scheduled for 2014.

        Rare D decays (theory) 20m
        Rare D decays might serve as a test of FCNC transition in the up-quark sector. The presence of new physics in these decays is rather difficult to detect due to the contributions of SM long distance dynamics. Basic features of rare charm meson transitions within the Standard model and beyond are discussed. Chances to observe new physics signals are considered for inclusive c-> u gamma and c -> u l+l- decays and exclusive D ->V gamma, D -> P l+ l-, D-> V l+l- and D -> l+ l- decays.

        Lepton Flavour Violation (theory) 20m
        The field of lepton flavor violation will live an era of unprecedented developments in the near future, with dedicated experiments in different fronts. The observation of a flavor violating process involving charged leptons would be a clear evidence of physics beyond the Standard Model, thus motivating the great effort in this direction. Furthermore, in case a positive signal is found, a proper theoretical understanding of the lepton flavor anatomy of a given model would become necessary. In this talk I will briefly review the current situation, emphasizing the most relevant theoretical and phenomenological aspects of several processes. Finally, I will discuss two topics that have received some attention recently: lepton flavor violation in low-scale seesaw models and lepton flavor violating Higgs decays.

        Muon LFV (experiment) 20m
        Search for the lepton flavor violation has long history and is now active area of the experimental search for physics beyond the Standard Model. Last year the MEG experiment, searching for the mu->e gamma decay, completed the data acquisition, leading to one of the most stringent constraints on building BSM models. The muon LFV search will be followed by several sophisticated experiments as well as the final result from MEG with double statistics, and new insights into physics must be brought from those experiments in 5 years from now. In this talk, we will review the status and future prospects of muon LFV experiments including MEG, MEG II, Mu3e, DeMee, COMET, and Mu2e.

        Tau LFV (experiment) 20m
        The tau lepton, the heaviest charged lepton in the third generation, is a sensitive probe to New Physics (NP). In particular, lepton flavor violating (LFV) tau decays are of great interest, as many NP models predict their branching fractions in a range accessible by current and near future experiments. They also provide information of NP, complementary to LFV processes in the muon. In this talk, we will summarize the present status of searches for tau LFV decays at Belle and BaBar, as well as LHCb. We will also briefly discuss future prospect in the near future experiments.

For the first time we include results obtained from a time integrated analysis of B+ -> DK+, D -> KS0Kpi decays; and of B0 -> DK∗0, D -> K+K-, pi+pi-, K+pi-, pi+K- decays; and from a time-dependent analysis of Bs0 -> DsK decays. The results represent the world's best single-experiment determination of gamma.

An outlook of the capabilities of LHCb is given with a number of direct CPV processes involving electro-weak and gluonic penguins and a measurement of gamma using tree diagrams as examples.

This large dataset will open up a new era of precision measurements in flavor physics. This talk will focus on the potential for a sub-degree precision measurement of the least constrained angle of the CKM unitarity triangle, gamma, and the impact on studies of charmless hadronic B decays.
