fB and fBs using NRQCD
نویسنده
چکیده
This talk summarizes the quenched calculation of fB and fBs presented in [1]. The heavy quark is simulated using an O(1/M) improved NRQCD action, and the tadpole improved clover action is used for the light quarks. The axial current includes the O(1/M) corrections in one-loop perturbation theory and the O(1/M) ones at tree-level. We discuss the various systematic effects and consistency checks made in the calculation.

B meson leptonic decay constant with quenched lattice NRQCD ( JLQCD Collaboration )
We present a lattice NRQCD study of the B meson decay constant in the quenched approximation with emphasis given to the scaling behavior. The NRQCD action and the heavy-light axial current we use include all terms of order 1/M and the perturbative O(αsa) and O(αs/M) corrections. Using simulations at three value of couplings β=5.7, 5.9 and 6.1 on lattices of size 123×32, 163×48 and 243×64, we fi...
متن کاملfB and the Heavy-light Spectrum from NRQCD
B physics is a subject of active research. The theoretical and experimental understanding of the B meson and b baryon spectrum is just beginning. Weak matrix elements of B mesons, e.g. fB, fBs , BB, and BBs are being studied to determine fundamental parameters of the Standard Model. This review summarizes the progress made in calculating the B spectrum and decay constants using the nonrelativis...
متن کاملProgress Calculating Decay Constants with NRQCD and AsqTad Actions
We combine a light AsqTad antiquark with a nonrelativistic heavy quark to compute the decay constants of heavy-light pseudoscalar mesons using the ensemble of 3-flavor gauge field configurations generated by the MILC collaboration. Preliminary results for fBs and fDs are given and status of the chiral extrapolation to fB is reported. We also touch upon results of the perturbative calculation wh...

We report results on fB and semi-leptonic B decay form factors using NRQCD. We investigate 1/M scaling behavior of decay amplitudes. For fB Effect of higher order relativistic correction terms are also studied.
متن کاملLattice Results for Heavy Light Matrix Elements
Lattice results for heavy light matrix elements are reviewed and some of their implications are very briefly discussed [1]. Despite the fact that in most cases the lattice results for weak matrix elements at the moment have only a modest accuracy of about 20–30% they already have important phenomenological repercussions; e.g. for Vtd/Vts, xs/xd and B → K ∗γ. I. As samples of “new” projects, I b...
