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− 1. 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. 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− 1, 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 ofpb.
