At the LHC, the two-photon production of charged pairs can be used to probe new physics. Indeed, it has unique signature and, for masses around 200-250 GeV, significant cross-sections. Using the adopted CalcHEP program, interfaced to the Pythia generator, first analysis (DEA report) has been performed of the two-photon chargino, slepton and charged higgs boson pairs in MSSM for several benchmark points. First sensitivities estimates will be explained as well as preliminary results from a 'complete' simulation through CMSSW. In the same way, discovery potentials of doubly charged higgs bosons via gamma-gamma interactions and consequences on lepton number conservation will be discussed.
