论文摘要
在具有光重力的暗物质的存在下，在多重TEV量表上寻找压缩的超对称性，可以在观察相关的脂肪喷射时获得巨大的隆起，而缺失的横向动量是在近来较重的近级最重的exay过程中产生的玻色子的标志。我们专注于随后的希格斯和/或$ z $玻色子的剂量衰变，从而在最终状态下至少产生了至少两种脂肪喷射和$ \ \ \ \ \ \ \ slashed {e} _t $。我们进行了一项详细的背景研究，该研究采用多变量分析，使用增强决策树，以提供强大的研究，以探索14 TEV LHC的发现潜力，考虑到满足所有理论和实验性约束的不同基准测试点。该频道提供了最佳的发现前景，并在$ \ Mathcal {l} = 200 $ fb $^{ - 1} $的集成光度内发现了大多数基准。研究运动学可观察物，以区分具有相似事件产量的压缩和未压缩光谱。
Search for compressed supersymmetry at multi-TeV scale, in the presence of a light gravitino dark matter, can get sizable uplift while looking into the associated fat-jets with missing transverse momenta as a signature of the boson produced in the decay process of much heavier next-to-lightest sparticle. We focus on the hadronic decay of the ensuing Higgs and/or $Z$ boson giving rise to at least two fat-jets and $\slashed{E}_T$ in the final state. We perform a detailed background study adopting a multivariate analysis using a boosted decision tree to provide a robust investigation to explore the discovery potential for such signal at 14 TeV LHC considering different benchmark points satisfying all the theoretical and experimental constraints. This channel provides the best discovery prospects with most of the benchmarks discoverable within an integrated luminosity of $\mathcal{L}=200$ fb$^{-1}$. Kinematic observables are investigated in order to distinguish between compressed and uncompressed spectra having similar event yields.
