Measurements of inclusive and differential cross-sections of $t\bar{t}{\hat{I}}^3$ production in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

Carmen Diez Pardos

Cross-section measurements of the associated production of a top quark pair and a photon ($t\bar{t}{\hat{I}}^3$) are performed with an integrated luminosity of 140 fb${}^{-1}$ of proton-proto…
