Inclusive and differential measurements of the $\mathrm{t}\bar{\mathrm{t}}\gamma$ cross section and the $\mathrm{t}\bar{\mathrm{t}}\gamma$ / $\mathrm{t}\bar{\mathrm{t}}$ cross section ratio in proton-proton collisions at $\sqrt{s}$ = 13 TeV

CMS Collaboration

Inclusive and differential cross section measurements of top quark pair ($\mathrm{t}\bar{\mathrm{t}}$) production in association with a photon ($\gamma$) are performed as a function of lepton, p…
