Three-loop anomalous dimensions of fixed-charge operators in the SM
In this Letter we consider renormalization of a class of scalar operators with fixed hypercharge Q within the Standard Model. We carry out explicit computation of the corresponding anomalous dimensions up to the three-loop order. In spite of the fact that our result is gauge-dependent, in the Landau...
