The data sample corresponds to an integrated luminosity of 77.5 fb$^{-1}$, collected by the CMS experiment during 2016 and 2017. The measurement is performed using final states containing three or four charged leptons (electrons or muons), and the Z boson is detected through its decay to an oppositely charged lepton pair. The production cross section is measured to be $\\sigma(\\mathrm{t\\bar{t}Z})$ $=$ 0.95 $\\pm$ 0.05 (stat) $\\pm$ 0.06 (syst) pb. For the first time, differential cross sections are measured as functions of the transverse momentum of the Z boson and the angular distribution of the negatively charged lepton from the Z boson decay. The most stringent direct limits to date on the anomalous couplings of the top quark to the Z boson are presented, including constraints on the Wilson coefficients in the framework of the standard model effective field theory.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t1","@type":"Dataset","description":"Measured absolute differential tt\u0304Z production cross section in the full phase space as a function of the transverse momentum of...","name":"Abs. diff. cross section: $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t2","@type":"Dataset","description":"Measured normalized differential tt\u0304Z production cross section in the full phase space as a function of the transverse momentum of...","name":"Norm. diff. cross section: $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t3","@type":"Dataset","description":"Measured absolute differential tt\u0304Z production cross section in the full phase space as a function of $\\cos\u03b8^{*}_{\\mathrm{Z}}$, compared to the...","name":"Abs. diff. cross section: $\\cos\u03b8^{*}_{\\mathrm{Z}}$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t4","@type":"Dataset","description":"Measured normalized differential tt\u0304Z production cross section in the full phase space as a function of $\\cos\u03b8^{*}_{\\mathrm{Z}}$, compared to the...","name":"Norm. diff. cross section: $\\cos\u03b8^{*}_{\\mathrm{Z}}$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t5","@type":"Dataset","description":"Covariance matrix of the measured absolute differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Covariance matrix: abs. $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t6","@type":"Dataset","description":"Correlation matrix of the measured absolute differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Correlation matrix: abs. $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t7","@type":"Dataset","description":"Covariance matrix of the measured normalized differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Covariance matrix: norm. $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t8","@type":"Dataset","description":"Correlation matrix of the measured normalized differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Correlation matrix: norm. $p_{\\mathrm{T}}(\\mathrm{Z})$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t9","@type":"Dataset","description":"Covariance matrix of the measured absolute differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Covariance matrix: abs. $\\cos\u03b8^{*}_{\\mathrm{Z}}$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t10","@type":"Dataset","description":"Correlation matrix of the measured absolute differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Correlation matrix: abs. $\\cos\u03b8^{*}_{\\mathrm{Z}}$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t11","@type":"Dataset","description":"Covariance matrix of the measured normalized differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Covariance matrix: norm. $\\cos\u03b8^{*}_{\\mathrm{Z}}$"},{"@id":"https://doi.org/10.17182/hepdata.91636.v2/t12","@type":"Dataset","description":"Correlation matrix of the measured normalized differential tt\u0304Z production cross section in the full phase space as a function of...","name":"Correlation matrix: norm. $\\cos\u03b8^{*}_{\\mathrm{Z}}$"}],"identifier":[{"@type":"PropertyValue","propertyID":"HEPDataRecord","value":"https://www.hepdata.net/record/ins1746445?version=2"},{"@type":"PropertyValue","propertyID":"HEPDataRecordAlt","value":"https://www.hepdata.net/record/91636"}],"inLanguage":"en","name":"Measurement of top quark pair production in association with a Z boson in proton-proton collisions at $\\sqrt{s} =$ 13 TeV","provider":{"@type":"Organization","name":"HEPData"},"publisher":{"@type":"Organization","name":"HEPData"},"url":"https://www.hepdata.net/record/ins1746445?version=2","version":2}
