MULTILEPTON SUSY SIGNALS FROM R-PARITY VIOLATION AT THE FERMILAB TEVATRON

The expected trilepton signals from ppBAR --> chi(1)+/-chi2(0) --> (chi1(0)l+/-nu) (chi1(0)l'+l'-) will be converted into hadronically quiet multilepton signals, if the two final chi1(0) have leptonic R-parity-violating (RPV) decays chi1(0) --> ll'nu. We make illustrative calculations of the acceptance for these spectacular RPV signals, and point out that distinctive multilepton signals are possible even when the R-conserving trilepton signals are blocked by the ''spoiler mode'' chi2(0) --> h0chi1(0). Other channels such as ppBAR --> chi1+/-chi2(0) --> (chi1(0)l+/-nu) (chi1(0)nunu), ppBAR --> chi1+/-chi1(0) --> (chi1(0)lnu)chi1(0), and ppBAR -> chi1+chi1- --> (chi1(0)l+nu) (chi1(0)l'-nu) can also give quiet mutlileptons from RPV. We investigate these signals in the context of supersymmetric models with radiative electroweak symmetry breaking, using examples in the low-tan beta lambda(t) fixed-point region.
