Description
In this talk I will present the relation between two distinct prescriptions for $\gamma_5$ in dimensional regularization – the Breitenlohner Maison t’Hooft Veltman (BMHV) scheme and Naive Dimensional Regularisation (NDR) in the SMEFT.
I will show how the quantum effective action can be translated between both schemes and present these translation rules for the Wilson Coefficients. I will conclude presenting a practical example of the map, namely the two-loop contributions from four-fermion operators to the running of $m_t,g_s$.
