Abstract

We consider the two-loop anomalous dimension for weak non-leptonic decays under the exchange of one gluon and one photon as in A. J. Buras, M. Jamin, M. Lautenbacher and P. Weisz:Nucl. Phys. B,400, 75 (1993). We prove the renormalization schemes HV, NDR, and the dimensional reduction are all physically compatible.
