$f_{B}$ and $f_{B_{s}}$ using NRQCD

arXiv:hep-lat/9810015 · doi:10.1016/S0920-5632(99)85076-2

Abstract

This talk summarizes the quenched calculation of $f_{B}$ and $f_{B_{s}}$ presented in hep-lat/9801038. The heavy quark is simulated using an $O (1/ M^{2})$ 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 $O (1/ M^{2})$ ones at tree-level. We discuss the various systematic effects and consistency checks made in the calculation.
