Higgs bosons: discovered and hidden, in extended supersymmetric standard models at the LHC

We investigate an extension of the Minimal Supersymmetric Standard Model (MSSM) contain- ing a SU(2) Higgs triplet of zero hypercharge and a gauge singlet. We focus on a scenario of this model which allows a light pseudoscalar and/or a scalar below 100 GeV in the spectrum, consistent with the most recent data from the LHC and the earlier data from the LEP experiments
