|Delta F| = 1 Nonleptonic Effective Hamiltonian in a Simpler Scheme
Abstract
We consider | F| = 1 (F = S,C or B) nonleptonic effective hamiltonian in a renormalization scheme which allows to consistently use fully anticommuting gamma5 at any number of loops, but at the leading order in the Fermi coupling GF. 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.
