摘要: The Next-to-Minimal Supersymmetric Standard Model (NMSSM) can incorporate inflation, where a combination of the Higgs-doublet fields plays role inflaton. At high scale, Higgs doublets are non-minimally coupled to supergravity; this coupling appears as an additional contribution $\mu$ term in low-energy effective superpotential and potentially changes physics at electroweak scale. In recent publication, we investigate extended parameter space model with respect collider phenomenology discuss scenarios which different from pure NMSSM. We analyse stability vacuum, masses neutralinos/charginos bosons well mixing decays bosons. Some important aspects study described following.
