PRODUCTION OF HEAVY SELECTRONS IN E(-)GAMMA COLLISIONS

We study the production and decay of heavy selectrons in the e(-)gamma mode of a linear collider of the next generation. The standard model backgrounds can be substantially reduced by appropriate kinematical cu ts. As a consequence, selectrons far heavier than the kinematical thre shold for pair production are shown to be easily discoverable for a co nsiderable part of the supersymmetry parameter space. We also describe a model-independent kinematical measurement of the mass of the lighte st neutralino.
