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...
متن کاملThe Constrained Exceptional Supersymmetric Standard Model
We propose and study a constrained version of the Exceptional Supersymmetric Standard Model (E6SSM), which we call the cE6SSM, based on a universal high energy scalar mass m0, trilinear scalar coupling A0 and gaugino mass M1/2. We derive the Renormalisation Group (RG) Equations for the cE6SSM, including the extra U(1)N gauge factor and the low energy matter content involving three 27 representa...
متن کاملSpectrum of Higgs Particles in the Exceptional Supersymmetric Standard Model
We discuss the spectrum of Higgs bosons in the framework of the exceptional supersymmetric standard model. The presence of a Z ′ and exotic particles predicted by the exceptional SUSY model allows the lightest Higgs particle to be significantly heavier than in the MSSM and NMSSM. When the mass of the lightest Higgs boson is larger than 135 − 140 GeV the heaviest scalar, pseudoscalar and charged...
متن کاملTheory and Phenomenology of an Exceptional Supersymmetric Standard Model
We make a comprehensive study of the theory and phenomenology of a low energy supersymmetric standard model originating from a string-inspired E6 grand unified gauge group. The Exceptional Supersymmetric Standard Model (ESSM) considered here is based on the low energy SM gauge group together with an extra Z ′ corresponding to an extra U(1)N gauge symmetry under which right–handed neutrinos have...
متن کاملPhenomenological Consequences of the Constrained Exceptional Supersymmetric Standard Model
The Exceptional Supersymmetric Standard Model (E6SSM) provides a low energy alternative to the MSSM, with an extra gauged U(1)N symmetry, solving the μ-problem of the MSSM. Inspired by the possible embedding into an E6 GUT, the matter content fills three generations of E6 multiplets, thus predicting exciting exotic matter such as diquarks or leptoquarks. We present predictions from a constraine...
