"Cut flow t+DM (mchi,mphi)=(1,50) GeV, scalar, DL" 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 dileptonic channel. The requirements listed up to and including the Z window cut are cumulative such that only the events and objects passing a given requirement are considered in subsequent requirements. The last four requirements show the separate yields after the cumulative requirements up to the Z window cut.

本数据集给出双轻子道（dileptonic channel）下，t+DM过程且标量媒介子（scalar mediator）信号假说为$(m_{chi},m_{phi})=(1,50), ext{GeV}$时的预期信号产额。该产额对应2016、2017及2018年取数时段，各时段的积分亮度分别为$36.3, ext{fb}^{-1}$、$41.5, ext{fb}^{-1}$及$59.7, ext{fb}^{-1}$，所有产额均为逐一应用各搜索筛选要求后的结果。
所列各筛选要求直至并包含Z窗截断（Z window cut）均为累积式要求：仅通过当前给定筛选要求的事例与粒子对象，才会被纳入后续筛选流程的考量范围。
最后四项筛选要求展示的，是在累积应用至Z窗截断（Z window cut）的所有筛选要求后，各独立分支的产额结果。
