Two-loop anomalous dimensions in the LEFT: dimension-six four-fermion operators in NDR

Abstract We derive the complete set of two-loop anomalous dimensions describing the mixing of four-fermion operators in the Low Energy Effective Field Theory (LEFT). The calculation is performed in Naive Dimensional Regularization with anticommuting γ 5 (the NDR scheme), and the results are given in...
