Exceptional Supersymmetric Standard Model
We discuss some phenomenological aspects of an E6 inspired supersymmetric standard model with an extra U(1)N gauge symmetry under which right-handed neutrinos have zero charge, allowing a conventional see-saw mechanism. The μ problem is solved in a similar way to the NMSSM, but without the accompanying problems of singlet tadpoles or domain walls. The above exceptional supersymmetric standard m...

There are several indications that the Majorana masses of the right-handed neutrino components, MR, are at the intermediate scale: MR ∼ (10 − 10) GeV or even lighter. The renormalization effects due to large Yukawa couplings of neutrinos from region of momenta MR ∼< q ∼< MG are studied in the supersymmetric standard model. It is shown that neutrino renormalization effect can increase the mb/mτ ...

We discuss the e+e− → (hA) → bbbb cross section in an Abelian extended SM. We work in that minimum of the scalar potential for which Higgs trilier coupling is greater than the soft mass parameters. We find that nex-to-lightest Higgs gives the essential contribution to the cross section in the small Z −Z ′ mixing angle and leptophobic Z ′ limit.

R-parity stands as an ad hoc assumption in the most popular version of the supersymmetric standard model. More than fifteen years’ studies of R-parity violations have been restricted to various limiting scenarios. We illustrate how the single-VEV parametrization provides a workable framework to analyze the phenomenology of the complete theory of supersymmetry without R-parity. In our comprehens...
متن کاملMinimal Supersymmetric Standard Model
In the minimal supersymmetric standard model, the Higgs sector has two unknown parameters, usually taken to be tanβ ≡ v2/v1 and mA, the mass of its one physical pseudoscalar particle. By minimizing the minimum of the Higgs potential along a certain direction in parameter space, it is shown that mA = MZ + radiative correction, and if one further plausible assumption is made, tanβ > √ 3. If there...
