| Abstract: The cross section for the production of a top quark-antiquark pair in association with a W boson in proton-proton collisions at a center-of-mass energy of 13 TeV is measured in a data sample recorded by the CMS experiment that corresponds to an integrated luminosity of 138 fb$^{-1}$. Events with two or three leptons, electrons or muons, and additional jets are selected. A cross section of 868 $\pm$ 40 (stat) $^{+52}_{-50}$ (syst) fb is measured. The production cross sections of a top quark pair with a W$^{+}$ and a W$^{-}$ boson are measured as 553$^{+30}_{-29}$ (stat) $^{+31}_{-30}$ (syst) fb and 343 $\pm$ 26 (stat) $\pm$ 25 (syst) fb, respectively, and the corresponding ratio of the two cross sections is 1.61$^{+0.15}_{-0.14}$ (stat) $^{+0.07}_{-0.05}$ (syst). The measured cross sections for the studied processes are in agreement with standard model predictions within two standard deviations. | ||
