Abstract

This talk summarizes results for all the scale independent renormalization constants for bilinear currents ( $Z_A$ , $Z_V$ , and $Z_S/Z_P$ ), the improvement constants ( $c_A$ , $c_V$ , and $c_T$ ), the quark mass dependence of $Z_O$ , and the coefficients of the equation of motion operators for $O(a)$ improved lattice QCD. Using data at $\beta=6.0$ , 6.2 and 6.4 we study the scaling behavior of these quantities and quantify residual discretization errors.
