LHC运行I后的pMSSM的经验和展望：中性子LSP
Lessons and Prospects from the pMSSM after LHC Run I: Neutralino LSP
摘要：
我们研究超对称签名在7，8和14 TeV的LHC采用19参数，R-宇称守恒p（现象学）MSSM，在与中性伴子LSP的情况下。我们的结果是通过一个快速的蒙特卡罗模拟的ATLAS超对称性分析套件。这个框架的灵活性，使我们能够同时研究各种各样的超对称性现象，并在现有的超对称性搜索分析的弱点进行探测。我们确定的sparticle质量的范围，要么不赞成或允许后，搜索与7和8 TeV的数据集相结合。我们发现，自然超对称模型轻方和胶子仍然是可行的。我们用300 fb $^{-1}$和3 ab $^{-1}$的积分亮度外推到14 TeV，并确定喷流+ MET的预期灵敏度，并停止对pMSSM参数空间的搜索。我们发现，高亮度LHC将是强大的探测超对称性与中性伴子LSP，并可以提供一个更明确的声明存在的自然超对称性。
英文摘要：
We study SUSY signatures at the 7, 8 and 14 TeV LHC employing the 19-parameter, R-Parity conserving p(henomenological)MSSM, in the scenario with a neutralino LSP. Our results were obtained via a fast Monte Carlo simulation of the ATLAS SUSY analysis suite. The flexibility of this framework allows us to study a wide variety of SUSY phenomena simultaneously and to probe for weak spots in existing SUSY search analyses. We determine the ranges of the sparticle masses that are either disfavored or allowed after the searches with the 7 and 8 TeV data sets are combined. We find that natural SUSY models with light squarks and gluinos remain viable. We extrapolate to 14 TeV with both 300 fb$^{-1}$ and 3 ab$^{-1}$ of integrated luminosity and determine the expected sensitivity of the jets + MET and stop searches to the pMSSM parameter space. We find that the high-luminosity LHC will be powerful in probing SUSY with neutralino LSPs and can provide a more definitive statement on the existence of natural Supersymmetry.
