The top-antitop quark (TOP TOPBAR) production cross section  is measured in proton-proton collisions at a centre-of-mass energy of 8 TeV with the CMS  experiment at the LHC, using a data sample corresponding to an integrated  luminosity of 5.3 fb-1. The measurement is performed by  analysing events with a pair of electrons or muons, or one electron and one  muon, and at least two jets, one of which is identified as originating from  hadronisation of a bottom quark. The measured cross section is 239 +- 2  (stat.) +- 11 (syst.) +- 6 (lum.) pb, for an assumed top-quark mass of  172.5 GeV, in agreement with the prediction of the standard model.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.64868.v1/t1","@type":"Dataset","description":"The total efficiencies etotal, i.e. the products of event acceptance, selection efficiency and branching fraction for the respective TOP TOPBAR...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.64868.v1/t2","@type":"Dataset","description":"The TOP TOPBAR cross section obtained by combining all final states.","name":"Table 2"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1275617?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/64868"}],"inLanguage":"en","name":"Measurement of the t t-bar production cross section in the dilepton channel in pp collisions at sqrt(s)=8 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1275617?version=1","version":1}
