Description
I will present the calculation of the h->2 gamma and h->Z gamma decays in the SM EFT at the 1-loop level. I will discuss the calculational setup including derivation of interaction vertices in physical field basis, choice of gauge fixing conditions and choice of the renormalization scheme. The final results for the Br(h->2 gamma) and Br(h->Z gamma) are given as compact semi-analytical expressions, which could be used to obtain constraints on the Wilson coefficients of the dimension-6 SMEFT operators.
