LHC RPV MSSM的覆盖率(带灯挡)

LHC Coverage of RPV MSSM with Light Stops

Jared A. Evans, Yevgeny Kats

摘要:

我们研究了最近的LHC搜索与R-宇称破坏(RPV)的超对称签名的敏感性。出于自然的希格斯势,这将有利于轻的第三代squarks,和严格的LHC的光谱上的界限,其中的胶子或第一代和第二代squarks是轻的,我们专注于对生产的光停止占主导地位的方案。我们考虑各种可能的直接和级联衰减的停止,涉及三线性RPV运营商。我们发现,在许多情况下,现有的搜索排除停止在自然质量范围和超越。然而,通常有很少或没有敏感性的情况下占主导地位的UDD运营商或LQD运营商涉及taus。我们提出了几个想法的搜索,可以解决现有的差距,这些信号的实验覆盖范围。

英文摘要:

We examine the sensitivity of recent LHC searches to signatures of supersymmetry with R-parity violation (RPV). Motivated by naturalness of the Higgs potential, which would favor light third-generation squarks, and the stringent LHC bounds on spectra in which the gluino or first and second generation squarks are light, we focus on scenarios dominated by the pair production of light stops. We consider the various possible direct and cascade decays of the stop that involve the trilinear RPV operators. We find that in many cases, the existing searches exclude stops in the natural mass range and beyond. However, typically there is little or no sensitivity to cases dominated by UDD operators or LQD operators involving taus. We propose several ideas for searches which could address the existing gaps in experimental coverage of these signals.
