Abstract
In this work we compute the leading logarithmic corrections to the b - -> sgamma decay in a dimensional scheme which does not require any def inition of the gamma5 matrix. The scheme does not exhibit unconsistenc ies and it is therefore a viable alternative to the 't Hooft Veltman s cheme, particularly in view of the next-to-leading computation. We con firm the recent results of Ciuchini et al.
