LHC上的R-奇偶破坏和直接Stau对产生

R-Parity Violation and Direct Stau Pair Production at the LHC

Herbert K. Dreiner, Victor Martin Lozano

摘要:

我们考虑了在LHC中R宇称违反超对称的LSP态的对产生。态通过LLWU算符衰变为标准模型轻子。使用CheckMATE,我们重新设计了多轻子搜索来测试这种情况。我们首次表明,使用这些分析的Stau质量可以被约束到345 GeV,这取决于Stau衰变模式,以及Stau混合角。然而,对于所有的情况下,有一个显着的差距之间的低LEP限制的Stau质量和LHC的敏感性的开始。这种方法可用于在未来限制的情况下,RPV轻子数违反模型的STAU部门。

英文摘要:

We consider pair production of LSP staus at the LHC within R-parity violating supersymmetry. The staus decay into Standard Model leptons through the LLĒ operator. Using CheckMATE we have recast multileptonic searches to test such scenarios. We show for the first time that using these analyses the stau mass can be constrained up to 345 GeV, depending on the stau decay mode, as well as the stau mixing angle. However, there is for all scenarios a significant gap between the lower LEP limit on the stau mass and the onset of the LHC sensitivity. This approach can be used in the future to constrain the stau sector in the context of RPV lepton-number violating models.
