Higgs boson couplings as a probe of new physics
Abstract
Precise measurements of various coupling constants of the 125 GeV Higgs boson h are one of the most important and solid methods to determine the structure of the Higgs sector. If we find deviations in the h coupling constants from the standard model predictions, it can be an indirect evidence of the existence of additional Higgs bosons in non-minimal Higgs sectors. Furthermore, we can distinguish non-minimal Higgs sectors by measuring a pattern of deviations in various h couplings. In this talk, we show patterns of the deviations in several simple non-minimal Higgs sectors, especially for the gauge hVV and Yukawa hff couplings. This talk is based on the paper [1].
