B meson decay constant with the Wilson and Clover heavy quark actions
Abstract
We present results of our quenched study of the B meson decay constant obtained with a parallel set of simulations with the Wilson and Clover actions at β=5.9, 6.1 and 6.3. Systematic errors associated with the large b-quark mass are analyzed within the Fermilab non-relativistic formalism. As our best estimate in the continuum limit we obtain fB=163 16 MeV and fBs=175 18 MeV with the Clover action.
