Scaling behavior of improvement and renormalization constants

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 $β=6.0$, 6.2 and 6.4 we study the scaling behavior of these quantities and quantify residual discretization errors.
