Sommaire:

I will discuss how the usual MSSM Higgs sector is modified when supersymmetry is assumed to be spontaneously broken at energies of the order of a few TeV. In such scenarios, it is possible to raise the tree level masses of all the scalars and easily provide a Standard Model like Higgs boson with the mass suggested by the last LHC results, i.e. around 125 GeV. Moreover, non-standard Higgs decays can take place and give rise to characteristic signatures at the LHC. In particular, I will focus on the possible decay of the Higgs boson into a gravitino and a neutralino, which subsequently decays promptly into another gravitino and a photon. I will discuss the prospects for the discovery of this decay in the monophoton + MET signature.
