Model independent evaluation of the Wilson coefficient of the Weinberg operator in QCD
Abstract We derive a Wilson coefficient of a CP-violating purely gluonic dimension-6 operator called the Weinberg operator G G G ∼ $$ \left(GG\overset{\sim }{G}\right) $$ generated by a scalar and two fermions at the two-loop level. We do not specify the representation of SU(3) c for the scalar and...
