We report a Monte Carlo study of the γγ → μmacr;R,L±μ̄ R,L.± reactions. The case of the left-handed scalar lepton is of particular interest because their main decay channel can be measured with a high precision. Final states containing up to 4 leptons and missing energy are also investigated. There, exotic shapes of the energy distributions appear as a consequence of cascade decay which would give a hint to recognize supersyinmotric processes by observing the shape of such distributions.
