Three loop [formula omitted] tensor current anomalous dimension in QCD
The anomalous dimensions of the general flavour non-singlet quark bilinear currents ψ ̄ γ [μ 1 …γ μ n] ψ are 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 f...
