    Martin Heck (Karlsruhe Institute of Technology)
    08/09/2014, 14:30
    WG2
    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...

  15. 139. The neutron lifetime
    Fred Wietfeldt (Tulane University)
    08/09/2014, 15:05
    WG1
    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...

    Gregorio HERDOIZA
    08/09/2014, 15:08
    WG2
    We discuss a lattice QCD computation of the B-meson decay constants by the ETM collaboration where suitable ratios allow to reach the bottom quark sector by combining simulations around the charm-quark mass with an exactly known static limit. The extrapolations to the continuum limit and to the physical point as well as other sources of systematic uncertainties are analysed. A comparison of...

    WG2
    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,...

    Alejandro Garcia (University of Washington)
    08/09/2014, 16:45
    WG1
    We will describe the extraction of Vud from nuclear beta decays. We will summarize recent progress in understanding possible sources of uncertainties, in particular, the isospin breaking corrections. We will present some existing tests of the latter and indicate the prospects for more stringent tests in the future.

  21. 51. Vcb experimental review
    Robin Glattauer (Vienna)
    08/09/2014, 16:45
    WG2
    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...

    Matthew David Moulson (INFN)

    WG1
    During the last few years, new experimental and theoretical results have allowed ever-more-stringent tests of the Standard Model to be performed using kaon decays. This overview of recent progress includes updated results for the evaluation of the CKM matrix element Vus from experimental kaon decay data, as well as related tests of CKM unitarity and gauge and lepton universality.

    Francesco SANFILIPPO
    08/09/2014, 17:30
    WG2
    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...

    Daping Du (University of Illinois, Urbana-Champaign)
    08/09/2014, 17:50
    WG2
    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...

  27. 46. Exclusive semileptonic B decays to high-mass charm hadrons
    Dr Florian Urs Bernlochner (Universitaet Bonn (DE))
    08/09/2014, 18:10
    WG2
    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...

  28. 144. Inclusion of isospin breaking effects in lattice simulations
    Antonin Portelli (University of Southampton)
    08/09/2014, 18:15
    WG1
    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...

  29. 118. Charm and bottom masses from QCD sum rules: new results and proper treatment of uncertainties
    Mr Bahman Dehnadi (University of Vienna)
    08/09/2014, 18:29
    WG2
    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...

    Guido Bell (University of Oxford)
    09/09/2014, 09:00
    WG5
    I will review the status of factorisation predictions for charmless hadronic B meson decays. In particular, I will report on recent progress in obtaining a full NNLO calculation, and I will elucidate how non-perturbative methods as well as experimental measurements can help to further constrain the theoretical predictions.

    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...

    Eli Ben Haim (Centre National de la Recherche Scientifique (FR))
    09/09/2014, 09:45
    WG5
    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...

    Marc Grabalosa Gandara (Univ. Blaise Pascal Clermont-Fe. II (FR))
    09/09/2014, 10:05
    WG5
    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...

    WG5
    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.
