Description
We calculate two-loop coefficient functions of the operators Gsub(μν)sup(a)Gsub(μν)sup(a), manti psipsi and m4 in the short-distance expansion for the T-product of two (pseudo)vector currents. The corrections are found to be relatively small, which indicates a good convergence of the corresponding pertubative series. (orig.)
