Abstract
We analyze the LHC phenomenology of —a version of the next-to-minimal supersymmetric standard model with a large-ish coupling. The scalar spectrum of the model contains a 200–300 GeV Higgs boson with standard-model like properties, and heavy -even and -odd Higgs bosons and with masses in 500–800 GeV range. We study the discovery potential of and in the decay chains and . The dominant backgrounds are the diffuse and productions, which can be suppressed by demanding reconstruction of ’s and ’s in intermediate states. The excess of signal events allows for a discovery of both and with over significance for of integrated luminosity.
