$O({\alpha }_{s}a)$ matching coefficients for axial vector current and $\Delta B$$=$2 operator

Abstract

We present a calculation of the perturbative matching coefficients including mixing with higher dimensional operators for the temporal component of the heavy-light axial current, $A_4$, and the $\Delta B=2$ operator, $O_S$. For $A_4^{static,NRQCD}$, calculations with various RG-improved gauge actions are peformed. Matching coefficients with NRQCD and heavy-clover actions are also compared.
