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.eninfo:eu-repo/semantics/openAccessPARTON DISTRIBUTIONSPLUS PLUSArticle2-s2.0-8495902063610.1103/PhysRevLett.116.05200226894703Q1WOS:000369495000006
