Measurement of the t t ¯ production cross section using events with one lepton and at least one jet in pp collisions at √s=13 TeV

A measurement of the t¯t production cross section at √ s = 13 TeV is presented using proton-proton collisions, corresponding to an integrated luminosity of 2.2 fb−1 , collected with the CMS detector at the LHC. Final states with one isolated charged lepton (electron or muon) and at least one je...
