Higgs Signals in a Type I 2HDM or with a Sister Higgs

摘要: In models where an additional SU(2)-doublet that does not have couplings to fermions participates in electroweak symmetry breaking, the properties of Higgs boson are changed. At tree level, neighborhood SM-like range parameter space, it is natural coupling vectors, cV, approximately constant, while fermions, cf, suppressed. This leads enhanced VBF signals gamma keeping other Higgses constant (such as WW* and ZZ*), suppressing higgs tau tau. Sizable tree-level effects often accompanied by light charged states, which lead important constraints from b s top H+, but also similarly sizable contributions inclusive h signal radiative effects. simplest model, this described a Type I 2HDM, supersymmetry naturally realized with "sister Higgs" fields. such scenario, states can contribute further fewer heavy flavor decays. With supersymmetry, Grand Unification motivates inclusion colored partner These G-quarks may provide evidence for model.
