Three loop <OVL STYLE="s">MSoverline tensor current anomalous dimension in QCD
Abstract
The anomalous dimensions of the general flavour non-singlet quark bilinear currents ψ¯γ[μ1...γμn]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 flavour singlet current is also discussed.
