Measurement of the top quark pair production cross section in proton-proton collisions at sqrt(s) = 13 TeV

Abstract

The top quark pair production cross section is measured for the first time in proton-proton collisions at sqrt(s) = 13 TeV by the CMS experiment at the CERN LHC, using data corresponding to an integrated luminosity of 43 inverse picobarns. 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.

Replaced with published version; this version corrects the luminosity in the arXiv metadata abstract from 42 to 43 inverse picobarns
