Supersymmetry signatures with tau jets at the Fermilab Tevatron - art. no.015001

We study the supersymmetry reach of the Fermilab Tevatron in channels conta ining both isolated leptons and identified tau jets. In the must challengin g case, where the branching ratios of gauginos to taus dominate, we find th at searches for two leptons, a tau jet and a large amount of missing transv erse energy have a much better reach than the classic trilepton signature. With a total integrated luminosity of L greater than or similar to 4fb(-1), the Tevatron will start extending the expected CERN LEP-II reach for super symmetry.
