Spontaneous R-parity breaking at hadron supercolliders

If supersymmetry (SUSY) is realized with spontaneous breaking of R-parity, there can be large rates for single sparticle production. We make a detailed study of the rates for Drell-Yan-like single chargino and single neutralino production at a hadron supercollider. The attainable rates are promising in view of the luminosities expected at these facilities. All observational restrictions from cosmology, astrophysics and laboratory are taken into account in our analysis, including the recent LEP results as well as neutrino physics constraints.
