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

description: 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 tt+DM $(m_{\chi},m_{a}) = (1,50)$ GeV pseudoscalar 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.
description: A search is performed for dark matter produced in association with a single top quark or a pair of top quarks using the data collected with the CMS detector at the LHC from proton-proton collisions at a center-of-mass energy of 13 TeV, corresponding to $138\,\text{fb}^{-1}$ of integrated luminosity. Various decay modes of the top quark are probed, resulting in three separate channels depending on the number of leptons in the final state, namely the all hadronic (zero lepton), single lepton (one lepton), and the dileptonic (two leptons) final states. The results are derived from the combination of these different categories. An excess of events with respect to the background-only prediction is searched for in events with a large imbalance in the transverse momentum. Novel multivariate techniques are used to take advantage of the differences in kinematic properties between the two dark-matter-associated production modes. No significant deviations with respect to the standard model predictions are observed. The results are interpreted in the context of a simplified model in which either a scalar or pseudoscalar mediator couples to top quarks and to dark matter fermions, as well as for axion-like particles that are coupled to top quarks and dark-matter fermions. The largest local significance of excess with respect to the standard model backround prediction is less than 2 standard deviations.
