Description

We use the Yang-Mills Gradient flow to study the NLO mixing of CP-violating operators in continuum QCD with special attention to Weinberg’s d=6 purely gluonic operator. This method allows for a clear derivation of the Wilson coefficients of the CP-violating effective action as they pertain to the renormalization group equation. This perturbative calculation is the first step towards a high-energy matching of matrix elements involving the CP-violating operators.
