Multilepton SUSY signals fromR-parity violation at the Fermilab Tevatron

The expected trilepton signals from pp¯→${\mathrm{\chi }}_1^{\pm }$ ${\mathrm{\chi }}_2^0$→(${\mathrm{\chi }}_1^0$ ${\mathit{l}}^{\pm }$ν) (${\mathrm{\chi }}_1^0$l${\mathcal{’}}^{+}$l${\mathcal{’}}^{\mathrm{-}}$) will be converted into hadronically quiet multilepton signals, if the two final ${\mathrm{\chi }}_1^0$ have leptonic R-parity-violating (RPV) decays ${\mathrm{\chi }}_1^0$→ll’ν. 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’’ ${\mathrm{\chi }}_2^0$→${\mathit{h}}^0$ ${\mathrm{\chi }}_1^0$. Other channels such as pp¯→${\mathrm{\chi }}_1^{\pm }$ ${\mathrm{\chi }}_2^0$→(${\mathrm{\chi }}_1^0$ ${\mathit{l}}^{\pm }$ν)(${\mathrm{\chi }}_1^0$νν), pp¯→${\mathrm{\chi }}_1^{\pm }$ ${\mathrm{\chi }}_1^0$→(${\mathrm{\chi }}_1^0$lν)${\mathrm{\chi }}_1^0$, and pp¯→${\mathrm{\chi }}_1^{+}$ ${\mathrm{\chi }}_1^{\mathrm{-}}$→(${\mathrm{\chi }}_1^0$ ${\mathit{l}}^{+}$ν)(${\mathrm{\chi }}_1^0$l${\mathcal{’}}^{\mathrm{-}}$ν) can also give quiet multileptons from RPV. We investigate these signals in the context of supersymmetric models with radiative electroweak symmetry...
