One-Loop Effective Actions

Apr 16, 2019, 12:00 PM


Dr Jérémie Quevillon (LPSC (CNRS))


In this talk, we present the universal one-loop effective action obtained by integrating out massive, non-degenerate multiplets, focusing on the coefficients of operators of dimension up to six composed of Standard Model fields. Our general results may be applied to loops of non-degenerate heavy fermions or bosons.
We discuss the relationship of our results (and their ongoing improvement) to several EFTs: the SM Effective Field Theory, EFTs for the gauge bosons of some generic gauge symmetry and EFTs based on a Two Higgs Doublet Model.
