GAMMA-GAMMA-PRODUCTION OF NON-STRONGLY INTERACTING SUSY PARTICLES AT HADRON COLLIDERS

Non-strongly interacting particles in supersymmetric theories - slepto ns, charginos/neutralinos, and charged Higgs bosons - are difficult to detect at the Large Hadron Collider. We therefore examine the possibi lity of producing particles of this type in virtual gammagamma collisi ons at the LHC. Since photons can be emitted from protons which do not break up in the radiation process, very clean events can be generated , compensating to some extent for the small event numbers. Higher rate s are expected, at the expense of stray hadrons, for events in which o ne or both protons break up.
