Associated slepton-neutralino and slepton-chargino production at CERN LEP on LHC

We examine for representative gaugino-Higgsino mixing scenarios slepton-neutralino and slepton-chargino production in deep inelastic ep scattering at \ensuremath{\surd}s =1.8 TeV. We find sneutrino-chargino production to be the dominant process with cross sections more than one order of magnitude bigger than those for slepton-squark production. Also for associated production of sneutrinos and Z-ino-like neutralinos the cross sections are at least comparble to those for l\ifmmode \tilde{}\else \~{}\fi{}q\ifmmode \tilde{}\else \~{}\fi{} production, whereas selectron-neutralino or selectron-chargino production is with cross sections significantly smaller than those for selectron-squark production less favorable. Typical signatures include events with up to four charged leptons, hadronic jets and, in some cases, gauge bosons.
