Higgs Quark Couplings in Susy with Cp and Flavor Violations
In minimal supersymmetric model (SUSY) with a light Higgs sector, explicit CP violation and most general flavor mixings in the sfermion sector, integration of the superpartners out of the spectrum induces potentially large contributions to the Yukawa couplings of light quarks via those of the heavier ones. These corrections can be sizeable even for moderate values of tan β, and remain nonvanish...
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...
متن کاملAnomalous Higgs Couplings
We review the effects of new effective interactions on the Higgs boson phenomenology. New physics in the electroweak bosonic sector is expected to induce additional interactions between the Higgs doublet field and the electroweak gauge bosons leading to anomalous Higgs couplings as well as to anomalous gauge–boson self–interactions. Using a linearly realized SU(2)L × U(1)Y invariant effective L...
متن کاملSUSY Decays of Higgs Particles
Among the possible decay modes of Higgs particles into supersymmetric states, neutralino and chargino decays play a prominent rôle. The experimental opportunities of observing such decay modes at LEP2 and at future ee linear colliders are analyzed within the frame of the Minimal Supersymmetric extension of the Standard Model. For heavy Higgs particles, the chargino/neutralino decay modes can be...
متن کاملConstraints on Charged - Higgs Couplings
Using the experimental value of the Et -KS mass difference, we derive constraints on charged-Higgs couplings in gauge theories of the weak and electromagnetic interactions. These bounds severely restrict the possible magnitude of charged-Higgs effects in K and D meson decays.' Our results are based on the observation that charge-Higgs exchange contributions to K"go mixing are of order l/g where...
