Gauge fixing and loop calculations in EFT

I will discuss the technically convenient setup for loop calculations in the EFT. First, I will present the proof that the R_xi gauge fixing can always be used in any EFT with linearly realised gauge symmetry and to any order in 1/Lambda expansion. Then, I will discuss the applications to SM-EFT on the example of systematic calculation of h->2 gamma and h->Zgamma decays: derivation of Feynman rules, gauge fixing, choice of renormalization scheme and final semi-numerical results.
