Heavy - light decay constants on the lattice
نویسنده
چکیده
We present results for the leptonic decays of heavy-light mesons in the quenched approximation and a preliminary result for fD s with dynamical fermions for N f = 2. We examine the systematic effects of extrapolating the decay constants from the charm to the bottom quark mass, and find this extrapolation to be under control. We present a preliminary result for f N f =2 Ds and compare to f N f =0 Ds matched to have the same lattice spacing set by the Sommer scale, r0. We find no significant difference.

Decay constants of P - wave heavy - light mesons from unquenched lattice QCD
We review some decays that require knowledge of the decay constants of 0 + heavy-light mesons. We compute the decay constants of P-wave heavy-light mesons from unquenched lattice QCD at a single lattice spacing. For the charm-strange meson we obtain the decay constant: fD s 0 + = 340(110) MeV using our normalisation conventions. We obtain the f static Ps (static-strange P-wave) decay constant a...
متن کاملHeavy-Light Mesons with Quenched Lattice NRQCD: Results on Decay Constants
We present a quenched lattice calculation of heavy-light meson decay constants, using non-relativistic (NRQCD) heavy quarks in the mass region of the b quark and heavier, and clover-improved light quarks. The NRQCD Hamiltonian and the heavy-light current include the corrections at first order in the expansion in the inverse heavy quark mass. We study the dependence of the decay constants on the...
متن کاملQuenched Chiral Corrections to Heavy-Light Decay Constants at Order 1/M
Quenched chiral perturbation is used to study the decay constants for heavy-light mesons beyond the leading order in 1/M . The results are used to estimate the error in quenched lattice calculations of the decay constants. For the double ratio R1 = (fDs/fD)/(fBs/fB) we find that the error is small — conservatively 5%, but likely smaller. We also find that quenching decreases the ratio fDs/fD re...
متن کاملB Decay Constants from NRQCD with Dynamical Fermions
We present a lattice investigation of the heavy-light meson decay constants using Wilson light quarks and NRQCD heavy quarks, partially including the effects of dynamical sea quarks. We calculate the pseudoscalar and vector decay constants over a wide range in heavy quark mass and are able to perform a detailed analysis of heavy quark symmetry. We find consistency between the extrapolation of t...
متن کاملLeptonic Decays of Heavy Quarks on the Lattice
The status of lattice calculations of heavy-light decay constants and of the B parameterBB is reviewed. After describing the lattice approach to heavy quark systems, the main results are discussed, with special emphasis on the systematic errors in present lattice calculations. A detailed analysis of the continuum limit for decay constants is performed. The implications of lattice results on stu...
