Precise calculations for decays of Higgs bosons in extended Higgs sectors
Abstract
We briefly introduce H-COUP3.0, which we developed for evaluating higher-order corrections to any Higgs boson decays in various extended Higgs sectors. Focusing on two Higgs doublet models (2HDMs), we then discuss how the non-decoupling effects of the additional Higgs bosons are significant in Higgs boson decays.
