In this work we give a detailed description of a method for the calculation of QCD corrections to electroweak processes in dimensional regularization that does not require any definition of the ys matrix in d dimensions. This method appears particularly convenient to limit the algebraic complexity of higher order calculations. As an example, we computer the leading logarithmic corrections to the b -> sy decay.
