The production of Z bosons is studied in the dimuon and dielectron decay channels in PbPb and pp collisions at $\\sqrt{s_{\\mathrm{NN}}}$ = 2.76 TeV, using data collected by the CMS experiment at the LHC. The PbPb data sample corresponds to an integrated luminosity of about $150~\\mu\\mathrm{b}^{-1}$, while the pp data sample collected in 2013 at the same nucleon-nucleon centre-of-mass energy has an integrated luminosity of $5.4~\\mathrm{pb}^{-1}$. The Z boson yield is measured as a function of rapidity, transverse momentum, and collision centrality. The ratio of PbPb to pp yields, scaled by the number of inelastic nucleon-nucleon collisions, is found to be $1.06\\pm0.05~\\mathrm{(stat)}\\pm0.08~\\mathrm{(syst)}$ in the dimuon channel and $1.02\\pm0.08~\\mathrm{(stat)}\\pm0.15~\\mathrm{(syst)}$ in the dielectron channel, for centrality-integrated Z boson production. This binary collision scaling is seen to hold in the entire kinematic region studied, as expected for a colourless probe that is unaffected by the hot and dense QCD medium produced in heavy ion collisions.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t1","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson pT for the...","name":"Table 1"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t2","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson pT for the...","name":"Table 2"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t3","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson rapidity for the...","name":"Table 3"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t4","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson rapidity for the...","name":"Table 4"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t5","@type":"Dataset","description":"Event centrality dependence of the $\\mbox{Z}\\rightarrow\\mu^{+}\\mu^{-}$ yields per MB event in PbPb collisions, divided by the expected average nuclear overlap...","name":"Table 5"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t6","@type":"Dataset","description":"Event centrality dependence of the $\\mbox{Z}\\rightarrow e^{+}e^{-}$ yields per MB event in PbPb collisions, divided by the expected average nuclear...","name":"Table 6"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t7","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson $p_{\\rm T}$...","name":"Table 7"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t8","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson $p_{\\rm T}$...","name":"Table 8"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t9","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson rapidity for...","name":"Table 9"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t10","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson rapidity for...","name":"Table 10"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t11","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson rapidity for...","name":"Table 11"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t12","@type":"Dataset","description":"The measured Z boson yields per MB event in PbPb collisions as a function of the Z boson $p_{\\rm T}$...","name":"Table 12"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t13","@type":"Dataset","description":"Event centrality dependence of the $\\mbox{Z}\\rightarrow l^{+}l^{-}$ yields per MB event in PbPb collisions, divided by the expected average nuclear...","name":"Table 13"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t14","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson rapidity for the...","name":"Table 14"},{"@id":"https://doi.org/10.17182/hepdata.66612.v1/t15","@type":"Dataset","description":"The measured Z boson production cross section in pp collisions as a function of the Z boson pT for the...","name":"Table 15"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1322726?version=1"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/66612"}],"inLanguage":"en","name":"Study of Z production in PbPb and pp collisions at sqrt(s[NN]) = 2.76 TeV in the dimuon and dielectron decay channels","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1322726?version=1","version":1}
