The analyzed data was recorded by the CMS experiment at the CERN LHC and corresponds to an integrated luminosity of 138 fb$^{-1}$. Events with two or three leptons (electrons and muons) and additional jets are selected. In events with two leptons, a multiclass neural network is used to distinguish between the signal and background processes. Events with three leptons are categorized based on the number of jets and of jets originating from b quark hadronization, and the lepton charges. The inclusive $t\\bar{t}$W production cross section in the full phase space is measured to be 868 $\\pm$ 40(stat) $\\pm$ 50(syst) fb. The $t\\bar{t}$W$^+$ and $t\\bar{t}$W$^-$ cross sections are also measured as 553 $\\pm$ 30(stat) $\\pm$ 30(syst) fb and 343 $\\pm$ 26(stat) $\\pm$ 25(syst) fb, respectively, and the corresponding ratio of the two cross sections is found to be 1.61 $\\pm$ 0.15(stat) $^{+0.07}_{-0.05}$(syst). The results are consistent with the standard model predictions within two standard deviations, and represent the most precise measurement of these cross sections to date.","hasPart":[{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t1","@type":"Dataset","description":"Distribution of the leading lepton transverse momemtum, prefit.","name":"Figure 2a"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t2","@type":"Dataset","description":"Distribution of the subleading lepton transverse momemtum, prefit.","name":"Figure 2b"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t3","@type":"Dataset","description":"Distribution of the leading jet transverse momemtum, prefit.","name":"Figure 2c"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t4","@type":"Dataset","description":"Distribution of the number of jets, prefit.","name":"Figure 2d"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t5","@type":"Dataset","description":"Distribution of the number of loose b-tagged jets, prefit.","name":"Figure 2e"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t6","@type":"Dataset","description":"Distribution of the missing transverse momemtum, prefit.","name":"Figure 2f"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t7","@type":"Dataset","description":"Distribution of the number of b-tagged jets, prefit.","name":"Figure 3"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t8","@type":"Dataset","description":"Distribution of the number of jets, prefit, validation region.","name":"Figure 4a"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t9","@type":"Dataset","description":"Distribution of the number of loose b-tagged jets, prefit, validation region.","name":"Figure 4b"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t10","@type":"Dataset","description":"Distribution of the leading jet transverse momemtum, prefit, validation region.","name":"Figure 4c"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t11","@type":"Dataset","description":"Distribution of the leading lepton transverse momemtum, prefit, validation region.","name":"Figure 4d"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t12","@type":"Dataset","description":"Distribution of the number of jets based on the number of b-tagged jets, prefit, control region enriched in WZ and...","name":"Figure 5"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t13","@type":"Dataset","description":"Distribution of the number of jets and b-tagged jets, prefit, control region enriched in ZZ and ttZ.","name":"Figure 6"},{"@id":"https://doi.org/10.17182/hepdata.127991.v2/t14","@type":"Dataset","description":"Number of predicted and observed events in the signal regions of the dilepton and trilepton channels.
