Description
The BMSSM (Beyond the MSSM) framework is an effective theory approach that encapsulates a variety of extensions beyond the MSSM with which it shares the same field content. The lightest Higgs mass can be much heavier than in the MSSM without creating a tension with naturalness or requiring superheavy stops. The phenomenology of the Higgs sector is at the same time much richer. I discuss here the different predicted rates in the LHC channels ZZ->4l, 2 photons, 2 photons + 2 jets and WW, together with the constraint stemming from the non observation of other Higgses in all channels. A special stress is put on the correlations between the signal channels and how they can help to exclude or discriminate among different theoretical models. I show furthermore how those results behave when applying constraints from dark matter and flavour physics.
