Abstract
The top quark pair production cross section is measured in proton-proton collisions at a center-of-mass energy of 5.02 TeV. The data were collected in a special LHC low-energy and low-intensity run in 2017, and correspond to an integrated luminosity of 302 pb. The measurement is performed using events with one electron and one muon of opposite charge, and at least two jets. The measured cross section is 60.7 5.0 (stat) 2.8 (syst) 1.1 (lumi) pb. To reduce the statistical uncertainty, a combination with the result in the single lepton + jets channel, based on data collected in 2015 at the same center-of-mass energy and corresponding to an integrated luminosity of 27.4 pb, is then performed. The resulting measured value is 63.0 4.1 (stat) 3.0 (syst+lumi) pb, in agreement with the standard model prediction of 66.8 pb.
