Inclusive and differential measurements of the $\mathrm{t}\bar{\mathrm{t}}{\hat{I}}^3$ cross section and the $\mathrm{t}\bar{\mathrm{t}}{\hat{I}}^3$ / $\mathrm{t}\bar{\mathrm{t}}$ 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 (${\hat{I}}^3$) are performed as a function of lepton,…
