We consider |∆F | = 1 (F = S, C or B) nonleptonic effective hamiltonian in a renor-malization scheme which allows to consistently use fully anticommuting γ 5 at any number of loops, but at the leading order in the Fermi coupling G F. We calculate two-loop anomalous dimensions and one-loop matching conditions for the effective operators in this scheme. Finally , we transform our results to one of the previously used renormalization schemes, and find agreement with the original calculations… CONTINUE READING
