Description

At the LHC, the two-photon production of charged supersymmetric pairs has a unique signature and, for masses below 200-250 GeV, significative cross- sections. In comparison to the nominal supersymmetric studies at the LHC it offers an interesting and very complementary potential. Using the adopted CalcHEP program, interfaced to the Pythia generator, first analysis has been performed of the two-photon chargino, slepton and charged higgs boson pairs in MSSM. The signal selection and suppression of the principal backgrounds due to W boson and lepton pair production have been studied at the generator level, resulting in first sensitivity estimates. Finally, the technical issues of the two-photon event selection in the harsh LHC environment are also discussed, and prospects for further developments are given.
