We present the MadAnalysis 5 implementation and validation of the CMS-EXO-17-030 search. The search targets pair-produced resonances, each of which decaying into three jets. The results are interpreted within an [Formula: see text]-parity violating supersymmetric (RPV SUSY) model, that predicts that pair-produced gluinos decay into three jets. This leads to a six-jet event. For this study, proton–proton collision data which was collected with the CMS detector in 2016 at a center of energy of 13 TeV is used, with a corresponding luminosity of 35.9 fb[Formula: see text]. In the search, the resonance mass is expected to range from 200 GeV to 2000 GeV so that the analysis comprises four signal regions (SRs). To validate the results, we have selected four gluino benchmark masses of 200, 500, 900, and 1600 GeV, each of which being representative of a given signal region (that are denoted SR1, SR2, SR3, and SR4). We have simulated signal events and calculated the signal acceptance within the MadAnalysis 5 framework in each signal region. To validate the recast, our predicted acceptances have been compared with the official values for those benchmark scenarios. An agreement at the level of about 10% has been obtained.

在 MadAnalysis 5 框架中实施 CMS-EXO-17-030 分析(产生一对共振,每个共振衰减为三个射流;35.9 fb-1)

我们介绍了 CMS-EXO-17-030 搜索的 MadAnalysis 5 实施和验证。搜索的目标是成对产生的共振,每个共振都衰减成三个喷流。结果在[公式:见文本]-违反超对称 (RPV SUSY) 模型中进行解释,该模型预测成对产生的 gluinos 衰变为三个喷射流。这导致了六次喷射事件。本研究使用 2016 年 CMS 探测器在 13 TeV 能量中心采集的质子-质子碰撞数据,对应的光度为 35.9 fb[公式:见正文]。在搜索中,预计共振质量范围为 200 GeV 至 2000 GeV,因此分析包括四个信号区域 (SR)。为了验证结果,我们选择了 200、500、900 和 1600 GeV 的 4 个 Gluino 基准质量,每个代表一个给定的信号区域(表示为 SR1、SR2、SR3 和 SR4)。我们模拟了信号事件并计算了 MadAnalysis 5 框架内每个信号区域的信号接受度。为了验证重铸,我们将预测接受度与这些基准场景的官方值进行了比较。已达成约 10% 水平的协议。
