论文摘要

我们调查了可以在LHC的高能升级时可以实现左右超对称性的最小实现的可能性,该LHC预计将以27 TEV的质量中心能量运行。这种最小的场景具有相对较轻的$ su(2)_r $ doubly带收费的希格斯玻色子,它可能主要腐烂到tau-lepton对。我们探讨了至少三个沉积的taus或至少有两个Hadronic Taus和一对相同签名的Lepton Lepton对组成的相关信号。我们的分析表明,由于相应的背景较大,以前的签名在信号上掌握了挑战,并且后者可以在几乎没有背景的环境中导致少数新的物理事件。但是,我们发现,在LHC的27 TEV升级时,可能会在质子 - 普罗顿碰撞的低光度下观察到由三个强调tau lept子组成的信号。

We investigate the possibility that a minimal realization of left-right supersymmetry can be reachable at a high-energy upgrade of the LHC, expected to operate at a center-of-mass energy of 27 TeV. This minimal scenario has a relatively light $SU(2)_R$ doubly-charged Higgs boson, which could decay dominantly into tau-lepton pairs. We explore the associated signals comprised of at least three hadronically-decaying taus, or with at least two hadronic taus and one same-sign-same-flavor charged lepton pair. Our analysis shows that the former signature is challenging to use for getting handles on the signal due to the large corresponding background, and that the latter one can lead to a handful of new physics events in an almost background-free environment. We however find that a signal comprised of three hadronically-decaying tau leptons is likely to be observed at a low luminosity of proton-proton collisions at a 27 TeV upgrade of the LHC.
