Three loop MSbar tensor current anomalous dimension in QCD
J. A. Gracey
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.
