"Cut flow t+DM (mchi,mphi)=(1,50) GeV, scalar, SL" of "Search for dark matter produced in association with one or two top quarks in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

Predicted signal yields for the 2016, 2017, and 2018 data-taking period, corresponding to $36.3\,\text{fb}^{-1}$, $41.5\,\text{fb}^{-1}$, and $59.7\,\text{fb}^{-1}$, respectively, after the application of each search requirement for the t+DM $(m_{\chi},m_{\phi}) = (1,50)$ GeV scalar mediator signal hypothesis for the single lepton channel. The requirements listed up to and including the $M_{T2}^{W}$ cut are cumulative such that only the events and objects passing a given requirement are considered in subsequent requirements. The last six requirements show the separate yields after the cumulative requirements up to the $M_{T2}^{W}$ cut.

针对单轻子道的t+DM（顶夸克-暗物质）标量媒介子信号假设（$(m_chi, m_phi)=(1,50), ext{GeV}$，即暗物质粒子质量$m_chi=1, ext{GeV}$、标量媒介子质量$m_phi=50, ext{GeV}$），在依次施加各项搜索筛选判据后，2016、2017、2018年数据采集时段对应的信号产额预测值，各时段对应的积分亮度分别为$36.3, ext{fb}^{-1}$、$41.5, ext{fb}^{-1}$与$59.7, ext{fb}^{-1}$。所列筛选判据直至并包含$M_{T2}^W$截断判据均为累积式的，即仅通过当前判据的事例与物理对象会被纳入后续判据的考量范围。最后六项筛选要求展示的是在完成直至$M_{T2}^W$截断判据的所有累积筛选要求后的独立产额。
