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

A search for the standard model production of four top quarks (pp → tt¯tt¯$$ \mathrm{t}\overline{\mathrm{t}}\mathrm{t}\overline{\mathrm{t}} $$) 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 …
