title: "MET distribution of the SL channel 1b 1FJ t&lt;=0 SR" of "Search for dark matter produced in association with one or two top quarks in proton-proton collisions at $\sqrt{s}$ = 13 TeV"

description: The post-fit $p_{\mathrm{T}}^{\text{miss}}$ distribution of the 1 b jet, $\geq 1$ forward jet, $t\leq 0$ signal region in the single lepton channel. A representative signal model distribution is shown for the scalar mediator interaction with $(m_{\chi},m_{\phi})=(1,100)$GeV and couplings set to unity. The grey dashed area in the upper panel represents the total uncertainty in all of the backgrounds and the chosen signal model, while in the lower panel it represents only the total uncertainty in the backgrounds.
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.
