B(s)0-mixing matrix elements from lattice QCD for the Standard Model and beyond

et al. 2016

We calculate-for the first time in three-flavor lattice QCD-the hadronic matrix elements of all five local operators that contribute to neutral B 0 -and B s -meson mixing in and beyond the Standard Model. We present a complete error budget for each matrix element and also provide the full set of correlations among the matrix elements. We also present the corresponding bag parameters and their correlations, as well as specific combinations of the mixing matrix elements that enter the expression for the neutral B-meson width difference. We obtain the most precise determination to date of the SU(3)-breaking ratio ξ = 1.206(18)(6), where the second error stems from the omission of charm sea quarks, while the first encompasses all other uncertainties. The threefold reduction in total uncertainty, relative to the 2013 Flavor Lattice Averaging Group results, tightens the constraint from B mixing on the Cabibbo-Kobayashi-Maskawa (CKM) unitarity triangle. Our calculation employs gauge-field ensembles generated by the MILC Collaboration with four lattice spacings and pion masses close to the physical value. We use the asqtad-improved staggered action for the light valence quarks, and the Fermilab method for the bottom quark. We use heavy-light meson chiral perturbation theory modified to include lattice-spacing effects to extrapolate the five matrix elements to the physical point. We combine our results with experimental measurements of the neutral B-meson oscillation frequencies to determine the CKM matrix elements |V td | = 8.00(34)(8) × 10 −3 , |V ts | = 39.0(1.2)(0.4) × 10 −3 , and |V td /V ts | = 0.2052(31)(10), which differ from CKM-unitarity expectations by about 2σ. These results and others from flavor-changing-neutral currents point towards an emerging tension between weak processes that are mediated at the loop and tree levels.

We clarify the radion superfield dependence of 5D N=1 superspace action. The radion is treated as a dynamical field and appears in the action with the correct mode function. Our derivation is systematic and based on the superconformal formulation of 5D supergravity. We can read off the couplings of the dynamical radion superfield to the matter superfields from our result. The correct radion mass can be obtained by calculating the radion potential from our superspace action.Comment: 5 pages, talks given by Y.Sakamura at PASCOS'05 (Geongju, Korea, May 30-June 4, 2005) and at SUSY'05 (Durham, U.K., July 18-23, 2005

The semileptonic decays and neutral mixing of B mesons have been studied in experiments at BaBar [3], Belle [4], CDF [5], DØ [6], and LHCb [7][8][9] and will become available from ongoing measurements at LHCb and the upcoming Belle II experiment. Errors from theory and experiment are commensurate and expected to be improved.…”

We report the status of an ongoing lattice-QCD calculation of form factors for exclusive semileptonic decays of B mesons with both charged currents (B → π ν, B s → K ν) and neutral currents (B → π + − , B → K + − ). The results are important for constraining or revealing physics beyond the Standard Model. This work uses MILC's (2+1+1)-flavor ensembles with the HISQ action for the sea and light valence quarks and the clover action in the Fermilab interpretation for the b quark. Simulations are carried out at three lattice spacings down to 0.088 fm, with both physical and unphysical seaquark masses. We present preliminary results for correlation-function fits. IntroductionSemileptonic decays of B (s) mesons are important to searches for new physics at the intensity frontier. Decays mediated at tree-level by charged currents (see Figure 1, left), namely B → π ν and B s → K ν , provide precise determinations of the CKM matrix element |V ub |. This element is crucial for testing CKM unitarity and thus important in the search for new physics. There are well-known discrepancies between inclusive and exclusive determinations of |V ub | [1]. Exclusive determinations combine theoretical calculations of nonperturbative form factors with experimental measurements of decay rates. This work seeks to further reduce the uncertainties from theory.Decays mediated by neutral currents (see Figure 1, right), namely B → π + − and B → K + − , provide precise tests of the Standard Model. Since flavor-changing neutral-current (FCNC) interactions are rare, they are sensitive to contributions from new physics. Tension currently exists between
