Search for the production of four top quarks in the single-lepton and opposite-sign dilepton final states in proton-proton collisions at sqrt(s) = 13 TeV


Based on: Some papers

Abstract: A search for the standard model production of four top quarks (pp ? tttt) is reported using single-lepton plus jets and opposite-sign dilepton plus jets signatures. Proton-proton collisions are recorded with the CMS detector at the LHC at a center-of-mass energy of 13 TeV in a sample corresponding to an integrated luminosity of 35.8 fb ? 1 . A multivariate analysis exploiting global event and jet properties is used to discriminate tttt from tt production. No significant deviation is observed from the predicted background. An upper limit is set on the cross section for tttt production in the s ...
