Measurements of inclusive and differential cross-sections of tt¯γ production in pp collisions at s = 13 TeV with the ATLAS detector

Inclusive and differential cross-sections are measured at particle level for the associated production of a top quark pair and a photon (tt¯γ$$ t\overline{t}\gamma $$). The analysis is performed using an integrated luminosity of 140 fb−1 of proton-proton collisions at a centre-of-mass energy of 13 T
