Lattice analysis of semi-leptonic form factors∗

چکیده
We present preliminary results from simulations done on 170 32×64 lattices at β = 6.0 using quenched Wilson fermions. This talk focuses on the Q behavior of the form-factors, extrapolation in quark masses, dependence on renormalization scheme, and comparison with heavy-quark effective theory (HQET). Even though we cannot estimate errors due to quenching and discretization, our results are consistent with experimental results for D decays. We present results for the Isgur-Wise function and estimate ξ(w = 1) = 0.97(6).

Leptonic and semi - leptonic B decays
We present results for the semi-leptonic and leptonic decays of B mesons. These non-perturbative matrix elements are important for constraining the CKM matrix. Results are presented for the pseudoscalar and vector decay constants, as well as flavour breaking ratios and heavy quark symmetry relations. We consider the chiral and momentum dependence of the semi-leptonic form factors of the decay B...

I review lattice quantum chromodynamics as relevant to the kaon system. Topics covered include the pseudoscalar masses and decay constants, the chiral effective lagrangian, f K / f π , semi-leptonic kaon decay form factors, and the neutral kaon oscillation parameter B K. c Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-ShareAlike Licence.
متن کاملLattice QCD and the Unitarity Triangle
Theoretical and computational advances in lattice calculations are reviewed, with focus on examples relevant to the unitarity triangle of the CKM matrix. Recent progress in semi-leptonic form factors for B! πlν and B!D lν, as well as the parameter ξ in B0-B̄0 mixing, are highlighted.
متن کاملComprehensive Bayesian Analysis of Rare (Semi)leptonic and Radiative B Decays
The available data on |∆B| = |∆S| = 1 decays are in good agreement with the Standard Model when permitting subleading power corrections of about 15% at large hadronic recoil. Constraining new-physics effects in C7, C9, C10, the data still demand the same size of power corrections as in the Standard Model. In the presence of chirality-flipped operators, all but one of the power corrections reduc...
