摘要:
Electroweak-inos 是电弱规范玻色子和 Higgs 玻色子的超对称伙伴,在超对称理论中具有特殊地位。它们复杂地混合成 chargino 和 neutralino 质量本征态,产生丰富的唯象学,这使得难以从 LHC 数据导出普适限制。本文中,我们在最小超对称标准模型框架下,利用 SModelS 软件包,对 promptly decaying electroweak-inos 的 LHC 约束进行全局分析。我们组合了 SModelS 中提供 electroweak-ino 效率图的多达 16 项 ATLAS 和 CMS 搜索,研究哪些组合能在参数空间不同区域最大化灵敏度,单项分析中数据的涨落如何影响全局似然,以及与逐项分析方法相比该组合所产生的排除能力。
英文摘要:
Electroweak-inos, superpartners of the electroweak gauge and Higgs bosons, play a special role in supersymmetric theories. Their intricate mixing into chargino and neutralino mass eigenstates leads to a rich phenomenology, which makes it difficult to derive generic limits from LHC data. In this paper, we present a global analysis of LHC constraints for promptly decaying electroweak-inos in the context of the minimal supersymmetric standard model, exploiting the SModelS software package. Combining up to 16 ATLAS and CMS searches for which electroweak-ino efficiency maps are available in SModelS, we study which combinations maximise the sensitivity in different regions of the parameter space, how fluctuations in the data in individual analyses influence the global likelihood, and what is the resulting exclusion power of the combination compared to the analysis-by-analysis approach.
