Query: Selectron Searches in $e^-e^-$ Scattering   We review the pair-production and decay of selectrons in $e^-e^-$ collisions
and show how the standard model backgrounds can be virtually eliminated with
polarized beams. The exceedingly simple analysis involved and the large sample
of background-free supersymmetric events make this linear collider operating
mode ideal for discovering selectrons and measuring the mass of the lightest
neutralino.
