Abstract
In this work we give a detailed description of a method for the calcul ation of QCD corrections to electroweak processes in dimensional regul arization that does not require any definition of the gamma s matrix i n d dimensions. This method appears particularly convenient to limit t he algebraic complexity of higher order calculations. As an example, w e compute the leading logarithmic corrections to the b --> s gamma dec ay.
