Three loop MSbar tensor current anomalous dimension in QCD

arXiv:hep-ph/0007171 · doi:10.1016/S0370-2693(00)00859-5

Abstract

The anomalous dimensions of the general flavour non-singlet quark bilinear currents ψγ^{[μ_1} ... γ^{μ_n]} ψare computed at three loops in quantum chromodynamics in the minimal subtraction scheme. The dimension of the tensor current emerges for the case n = 2 and the anomalous dimension for the general flavour singlet current is also discussed.
