Abstract: | Working in a softly broken supersymmetricSU(2)×U(1) standard model with the photino as lightest SUSY-particle ((m_{bar gamma } leqq 10GeV)) differential and total rates for the decay (Z^0 to l^ + l^ - tilde gamma tilde gamma ) as functions of various parameters of the model are presented. The decay involves intermediate scalar leptons and the total rate strongly depends on their masses. The results indicate that for a scalar lepton mass less than 70GeV this process might still be seen at SLC and CERN LEP I. |
