Abstract: (APS)
We study coupling constants of the standard model-like Higgs boson with the gauge bosons hZZ and hWW and fermions hff¯ in the general Higgs sector which contains higher isospin representations with arbitrary hypercharge. In the Higgs sectors with exotic Higgs representations, the hZZ and hWW coupling constants can be larger than those in the standard model. We calculate deviations in the Higgs boson couplings from standard model values in the model with a real or complex triplet field, the Georgi-Machacek model and the model with a septet scalar field. We also study deviations in the event rates of h→ZZ*, h→WW*, h→γγ, h→bb¯ and h→ττ channels.Note:
