The top quark pair production cross section is measured for the first time in proton-proton collisions at s√=13  TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43  pb−1. The measurement is performed by analyzing events with at least one electron and one muon of opposite charge, and at least two jets.

Abstract

The top quark pair production cross section is measured for the first time in proton-proton collisions at s√=13  TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43  pb−1. The measurement is performed by analyzing events with at least one electron and one muon of opposite charge, and at least two jets. The measured cross section is 746±58(stat)±53(syst)±36(lumi)  pb, in agreement with the expectation from the standard model.
