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 $138\,\text{fb}^{-1}$. Events with two or three leptons, electrons or muons, and additional jets are selected. A cross section of $868\pm40\,\text{(stat)}^{+52}_{-50}\,\text{(syst)}\,\text{fb}$ is measured. The production cross sections of a top quark pair with a $\mathrm{W^{+}}$ and a $\mathrm{W^{-}}$ boson are measured as $553^{+30}_{-29}\,\text{(stat)}^{+31}_{-30}\,\text{(syst)}\,\text{fb}$ and $343\pm26\,\text{(stat)}\pm25\,\text{(syst)}\,\text{fb}$, respectively, and the corresponding ratio of the two cross sections is $1.61^{+0.15}_{-0.14}\,\text{(stat)}^{+0.07}_{-0.05}\,\text{(syst)}$. The measured cross sections for the studied processes are in agreement with standard model predictions within two standard deviations.
