We look at the problem of QCD mixing between the four-quark operators and the {ital b}{r arrow}{ital s}{gamma} dipole operators in terms of extra {epsilon}-scalar interactions that distinguish the dimensional reduction and the naive dimensional regularization methods. We find that the mixings are the same in both methods provided that only (4{minus}{epsilon})-dimensional four-quark operators are retained. |
