The data set used corresponds to an integrated luminosity of 35.9 fb-1 recorded with the CMS detector at the LHC. Whereas previous searches for neutral scalar or pseudoscalar mediators considered dark matter production in association with a top quark pair only, this analysis also includes production modes with a single top quark. The results are derived from  the combination of multiple selection categories that are defined to target either the single top quark or the top quark pair signature. 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 a scalar or pseudoscalar mediator particle  couples to a top quark and subsequently decays into dark matter particles. Scalar and  pseudoscalar mediator particles with masses below 290 and 300 GeV, respectively, are  excluded at 95% confidence level, assuming a dark matter particle mass of 1 GeV and  mediator couplings to fermions and dark matter particles equal to unity.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.88882.v1/t1","@type":"Dataset","description":"Background-only post-fit $p_{T}^{miss}$ distributions for the CRs of the SL selection.
