Signatures with at least 2 jets and large missing transverse momentum are categorized into events with 0, 1, or 2 leptons. New results for regions of parameter space where the kinematical properties of top squark pair production and top quark pair production are very similar are presented. Depending on the model, the combined result excludes a top squark mass up to 1325 GeV for a massless neutralino, and a neutralino mass up to 700 GeV for a top squark mass of 1150 GeV. Top squarks with masses from 145 to 295 GeV, for neutralino masses from 0 to 100 GeV, with a mass difference between the top squark and the neutralino in a window of 30 GeV around the mass of the top quark, are excluded for the first time with CMS data. The results of theses searches are also interpreted in an alternative signal model of dark matter production via a spin-0 mediator in association with a top quark pair. Upper limits are set on the cross section for mediator particle masses of up to 420 GeV.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t1","@type":"Dataset","description":"Leading lepton ${p}_{T}$ distribution of data and MC events in the signal region with the signal stacked on top of...","name":"Figure 3a"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t2","@type":"Dataset","description":"${m}_{T2}$ distribution of data and MC events in the signal region with the signal stacked on top of the background...","name":"Figure 3b"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t3","@type":"Dataset","description":"${H}_{T}$ distribution of data and MC events in the signal region with the signal stacked on top of the background...","name":"Figure 3c"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t4","@type":"Dataset","description":"${p}_{T}^{miss}$ distribution of data and MC events in the signal region with the signal stacked on top of the background...","name":"Figure 3d"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t5","@type":"Dataset","description":"${p}_{T}^{miss}$ normalized distribution for signal points with different top squark and neutralino masses and SM ttbar events are compared.","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t6","@type":"Dataset","description":"${m}_{T2} (e\\mu)$ normalized distribution for signal points with different top squark and neutralino masses and SM ttbar events are compared.","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t7","@type":"Dataset","description":"$\\Delta\\eta (e\\mu)$ normalized distribution for signal points with different top squark and neutralino masses and SM ttbar events are compared.","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t8","@type":"Dataset","description":"$\\Delta\\phi (e\\mu)$ normalized distribution for signal points with different top squark and neutralino masses and SM ttbar events are compared.","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t9","@type":"Dataset","description":"Normalized DNN score distribution in the signal region for two mass hypotheses to compare signal and ttbar background: $m_{LSP}=$ 50...","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t10","@type":"Dataset","description":"Post-fit DNN score distributions in the signal region with the signal superimposed and scaled by a factor of 20 for...","name":"Figure 6a"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t11","@type":"Dataset","description":"Post-fit DNN score distributions in the signal region with the signal superimposed and scaled by a factor of 20 for...","name":"Figure 6b"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t12","@type":"Dataset","description":"Post-fit DNN score distributions in the signal region with the signal superimposed and scaled by a factor of 20 for...","name":"Figure 6c"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t13","@type":"Dataset","description":"Post-fit DNN score distributions in the signal region with the signal superimposed and scaled by a factor of 20 for...","name":"Figure 6d"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t14","@type":"Dataset","description":"Upper limit at 95% CL on the signal cross section as a function of the top squark and neutralino masses....","name":"Figure 7"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t15","@type":"Dataset","description":"Upper limit at 95% CL on the signal cross section as a function of the top squark mass for mass...","name":"Figure 8a"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t16","@type":"Dataset","description":"Upper limit at 95% CL on the signal cross section as a function of the top squark mass for mass...","name":"Figure 8b"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t17","@type":"Dataset","description":"Upper limit at 95% CL on the signal cross section as a function of the top squark mass for mass...","name":"Figure 8c"},{"@id":"https://doi.org/10.17182/hepdata.116374.v1/t18","@type":"Dataset","description":"Summary of the contributions of the experimental uncertainties in the DNN score distribution for signal and the ttbar background.
