我们基于 SUSY 尺度上的 14 个不相关的质量参数，提出了 MSSM 一般实现中出现的可能特征。通过假设具有相同量子数的前两代费米子具有简并性，可以减少一般 MSSM 的参数。我们还假设中性希格斯诺子和带电希格斯诺子之间不存在质量分裂。我们确实允许第三代 sfermons 单独的软中断条款。我们考虑了所有可能的结果 14 美元！ \approx 9 \cdot10^{10}$ 相关质量排序并检查主要的衰变级联和相应的对撞机签名。在确定主导衰变模式时，我们假设超粒子之间的混合是次主导的。作为首选特征，我们考虑带电轻子、缺失横向动量、喷流以及 $W、Z$ 或希格斯玻色子。我们还包括双线性和三线性 R 奇偶校验违规的情况，并表明可以使用特定的签名来区分不同的场景。
We present the possible signatures appearing in general realizations of the MSSM based on 14 unrelated mass parameters at the SUSY scale. The parameters of the general MSSM are reduced by assuming a degeneracy of the sfermions of the first two generations with the same quantum numbers. We also assume no mass-splitting between neutral and charged Higgsinos. We do allow for separate soft breaking terms for the third generation sfermons. We consider all possible resulting $14! \approx 9 \cdot10^{10}$ relevant mass orderings and check for the dominant decay cascades and the corresponding collider signatures. In determining the dominant decay modes we assume that mixing between sparticles is sub-dominant. As preferred signatures, we consider charged leptons, missing transverse momentum, jets, and $W, Z$ or Higgs bosons. We include also the cases of bi- and trilinear R-parity violation and show that specific signatures can be used to distinguish the different scenarios.
