چکیده
We discuss in detail the calculation of the leading order QCD corrections to the Effective Hamiltonian which governs b → s γ and b → s g transitions in three different regularization schemes (HV, NDR and DRED). We show that intermediate stages of the calculation do depend on the regularization, but the same scheme independent coefficients can be obtained in all the considered schemes. A detailed discussion of the results already present in the literature is also given.

A particular U(N) gauge theory defined on the three dimensional dodecahedral lattice is shown to correspond to a model of oriented self-avoiding surfaces. Using large N reduction it is argued that the model is partially soluble in the planar limit. * Physique Théorique CNRS. ** Laboratoire de l’Institut de Recherche Fondamentale du Commissariat à l’Energie
