Qcd Corrections To Electroweak Processes In An Unconventional Scheme - Application To the B->s gamma Decay

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 gamma s matrix in d dimensions. This method appears particularly convenient to limit the algebraic complexity of higher order calculations. As an example, we compute the leading logarithmic corrections to the b --> s gamma decay
