The normalised differential top quark-antiquark production cross section is measured as a function of the jet multiplicity in proton-proton collisions at a centre-of-mass energy of 7 TeV at the LHC with the CMS detector. The measurement is performed in both the dilepton and lepton+jets decay channels using data collected in 2011 corresponding to an integrated luminosity of 5.0 inverse femtobarns.  Using a procedure to associate jets to decay products of the top quarks, the differential top quark-antiquark production cross section is also determined as a function of the additional jet multiplicity in the lepton+jets channel.  \n\nFurthermore, the fraction of events with no additional jets is measured in the dilepton channel, as a function of the threshold on the jet transverse momentum.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t1","@type":"Dataset","description":"Normalised differential TOP TOPBAR production cross section as a function of the jet multiplicity for jets with PT(JET) > 30...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t2","@type":"Dataset","description":"Normalised differential TOP TOPBAR production cross section as a function of the jet multiplicity for jets with PT(JET) > 60...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t3","@type":"Dataset","description":"Normalised differential TOP TOPBAR production cross section as a function of the jet multiplicity for jets with PT(JET) > 35...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t4","@type":"Dataset","description":"Normalised differential TOP TOPBAR production cross section as a function of the number of additional jets with PT(JET) > 30...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t5","@type":"Dataset","description":"Measured gap fraction in the dilepton channel as a function of the additional jet transverse momentum, GAPFRAC(PT) = N(PT)/N(TOTAL) where...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.64426.v1/t6","@type":"Dataset","description":"Measured gap fraction in the dilepton channel as a function of the scalar sum of the transverse momentum of the...","name":"Table 6"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1290126?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/64426"}],"inLanguage":"en","name":"Measurement of jet multiplicity distributions in t t-bar production in pp collisions at $\\sqrt{s}$ = 7 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1290126?version=1","version":1}
