Perturbative renormalization factors for generic Δs=2 four-quark operators in domain-wall QCD with improved gauge action
Yousuke Nakamura, Yoshinobu Kuramashi
Abstract
We calculate one-loop renormalization factors of generic DeltaS=2 four-quark operators for domain-wall QCD with the plaquette gauge action and the Iwasaki gauge action. The renormalization factors are presented in the modified minimal subtraction (MS-bar) scheme with the naive dimensional regularization. As an important application we show how to construct the renormalization factors for the operators contributing to K0-K0bar mixing in the supersymmetric models with the use of our results.
