中文摘要	The discovery of a standard model (SM)-like Higgs boson with a relatively heavy mass m h and hints of di-photon excess has deep implication to supersymmetric standard models (SSMs). We consider the SSM extended with hypercharge +/- 1 triplets, and investigate two scenarios of it: (A) triplets significantly couple to the Higgs doublets, which can substantially raise m(h) and simultaneously enhance the Higgs to di-photon rate via light chargino loops; (B) oppositely, these couplings are quite weak and thus m h can not be raised. But the doubly-charged Higgs bosons, owing to the gauge group structure, naturally interprets why there is an excess rather than a deficient of Higgs to di-photon rate. Additionally, the pseudo Dirac triplet fermion is an inelastic non-thermal dark matter candidate. Light doubly-charged particles, especially the doubly-charged Higgs boson around 100GeV in scenario B, are predicted. We give a preliminary discussion on their search at the LHC.
