Abstract: | We analyze the associated production at future high-energy e + e - colliders, of first generation sleptons with neutralinos and charginos in the modes e + e - and , in the framework of the minimal supersymmetric extension of the standard model. We show that the production rates, in particular for associated production of right-handed selectrons and the lightest neutralino which in general is the first accessible kinematically, can be much larger than the corresponding ones for second and third generation scalar leptons and for scalar quarks. With the high luminosities expected at these colliders, the detection of first generation sleptons with masses significantly above the kinematical two-body threshold, , is thus possible in favorable regions of the parameter space.
