Approaching robust EFT limits for CP-violation in the Higgs sector


Based on: arXiv:1901.05982
and arXiv:1901.04567

Abstract: Constraining CP-violating interactions in e ective u000Celd theory (EFT) of dimension six faces two challenges. Firstly, degeneracies in the multi-dimensional space of Wilson coe cients have to be lifted. Secondly, quadratic contributions of CP-odd dimension six operators are di fficult to disentangle from squared contributions of CP-even dimension six operators and from linear contributions of dimension eight operators. Both of these problems are present when new sources of CP-violation are present in the interactions between the Higgs boson and heavy strongl ...
