 1 TUMASYAN 2021H measured fiducial inclusive and differential cross-sections for ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit \gamma}}$ at 13 TeV with 137 fb${}^{-1}$ of data. The results are in agreement with the SM predictions. The results are used to constrain anomalous couplings of the top quark in the SMEFT framework.
 2 AABOUD 2019AD measured fiducial inclusive and differential cross-sections for ${{\mathit p}}$ ${{\mathit p}}$ $\rightarrow$ ${{\mathit t}}{{\overline{\mathit t}}}{{\mathit \gamma}}$ at 13 TeV with 36.1 fb${}^{-1}$ of data. The results are in agreement with the theoretical predictions.
