Heavy-Light Matrix Elements with the Wilson Quark Action

Abstract

Status report is made of our quenched study of heavy-light matrix elements employing the Wilson quark action for heavy quark. Results obtained up to now with 200 configurations at β=6.1 on a 243×64 lattice and with 100 configurations at β=6.3 on a 323 ×80 lattice suggest that the pseudoscalar decay constant varies little over this range of β in both charm and bottom regions. Results for the B parameter are also reported.
