标题： Multilepton SUSY signals from R-parity violation at the Tevatron

摘要： 从$p \bar p \to \chi^\pm_1\chi^0_2 \to (\chi^0_1\ell^\pm\nu) (\chi^0_1\ell'^+\ell'^-) $预期的三轻子信号，如果两个最终的$\chi^0_1$具有轻子的$R$-宇称破坏（RPV）衰变$\chi^0_1 \to \ell \ell' \nu$，将会被转换为强子安静的多轻子信号。我们对这些引人注目的RPV信号的接受度进行了示例计算，并指出即使由“干扰模式”$\chi^0_2 \to h^0 \chi^0_1$阻断了$R$-守恒的三轻子信号，也可能出现独特的多轻子信号。 其他通道如 $p\bar p\to \chi_1^\pm \chi_2^0 \to (\chi_1^0\ell^\pm\nu) (\chi_1^0\nu\nu)$, $p\bar p\to \chi_1^\pm \chi_1^0 \to (\chi_1^0\ell\nu)\chi_1^0$ 和 $p\bar p\to\chi_1^+\chi_1^-\to(\chi_1^0\ell^+\nu)(\chi_1^0\ell'^-\nu)$也可以从RPV中给出安静的多轻子信号。 我们在具有辐射电弱对称性破缺的超对称模型背景下研究这些信号，以低-$\tan\beta$ $\lambda_t$ 固定点区域为例。 显示英文摘要

摘要： The expected trilepton signals from $p \bar p \to \chi^\pm_1\chi^0_2 \to (\chi^0_1\ell^\pm\nu) (\chi^0_1\ell'^+\ell'^-) $ will be converted into hadronically quiet multilepton signals, if the two final $\chi^0_1$ have leptonic $R$-parity-violating (RPV) decays $\chi^0_1 \to \ell \ell' \nu$. 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" $\chi^0_2 \to h^0 \chi^0_1$. Other channels such as $p\bar p\to \chi_1^\pm \chi_2^0 \to (\chi_1^0\ell^\pm\nu) (\chi_1^0\nu\nu)$, $p\bar p\to \chi_1^\pm \chi_1^0 \to (\chi_1^0\ell\nu)\chi_1^0$ and $p\bar p\to\chi_1^+\chi_1^-\to(\chi_1^0\ell^+\nu)(\chi_1^0\ell'^-\nu)$ can also give quiet multileptons 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.
