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 ${\hat{I}}^2=6.1$ on a $24^3\times 64$ lattice and with 100 configurations at ${\hat{I}}^2=6.3$ on a $32^3\times 80$ lattice suggest that the pseudoscalar decay constant varies little over this range of ${\hat{I}}^2$ in both charm and bottom regions. Results for the $B$ parameter are also reported.
