Signatures of Supersymmetry and Yukawa Unification in Higgs Decays
We show that the branching ratio Rb/τ ≡ BR(h → b̄b)/BR(h → ττ) of the Higgs boson h may usefully differentiate between the Higgs sectors of the Minimal Supersymmetric Standard Model (MSSM) and non–supersymmetric models such as the Standard Model or its two Higgs doublet extensions. Although at tree level Rb/τ is the same in all these models, only in the MSSM can it receive a large radiative corr...
متن کاملThe Higgs - Yukawa model in curved spacetime
The Higgs-Yukawa model in curved spacetime (renormalizable in the usual sense) is considered near the critical point, employing the 1/N–expansion and renormalization group techniques. By making use of the equivalence of this model with the standard NJL model, the effective potential in the linear curvature approach is calculated and the dynamically generated fermionic mass is found. A numerical...
متن کاملYukawa alignment in the two-Higgs-doublet model
In multi-Higgs-doublet models the alignment in flavor space of the relevant Yukawa matrices guarantees the absence of tree-level flavor-changing couplings of the neutral scalar fields. We analyze the consequences of this condition within the two-Higgs-doublet model and show that it leads to a generic Yukawa structure which contains as particular cases all known specific implementations of the m...
متن کاملOn the Phase Diagram of the SU ( 2 ) Adjoint Higgs Model in 2 + 1 Dimensions
The phase diagram is investigated for SU(2) lattice gauge theory in d = 3, coupled to adjoint scalars. For small values of the quartic scalar coupling, λ, the transition separating Higgs and confinement phases is found to be first-order, in agreement with earlier work by Nadkarni. The surface of second-order transitions conjectured by Nadkarni, however, is shown instead to correspond to crossov...
متن کاملHiggs-dependent Yukawa couplings
We consider the possibility that the Yukawa couplings depend on the Higgs field, with the motivation of generating the fermion mass hierarchy through appropriate powers of the Higgs vacuum expectation value. This leads to drastic modifications of the Higgs branching ratios, new Higgs contributions to various flavor-violating processes, and observable rates for the top quark decay t → hc. The un...
