Summary of ATLAS and CMS measurements of ttbarX (X=W, Z or γ) cross sections at 13 TeV. The ttbarW and ttbarZ cross section measurements are compared to the NLO QCD and EW theoretical calculation complemented with NNLL resummation, while the ttbarγ cross section measurement is compared to the NLO QCD theoretical calculation. "Vis 1", "Vis 2", and "Vis 3" highlight that the relevant phase space used for the ATLAS and CMS ttbarγ measurements are different. The theory prediction and experimental result of the ATLAS measurement ttbarγ+tWγ process is multiplied by a factor 20, and the result for the CMS is multiplied by a factor of 5 to allow for easy visualization on the same scale. The theory band represents uncertainties due to renormalisation and factorisation scales and parton density functions. Complementary theory predictions for the ttbarW and ttbarZ processes are also available in: A. Broggio et al., JHEP 08 (2019) 039 and arXiv:1610.07922. PNG November 2022 |
