Measurement of the inclusive and differential $\mathrm{t}\bar{\mathrm{t}}\gamma$ cross sections in the dilepton channel and effective field theory interpretation in proton-proton collisions at $\sqrt{s}=$ 13 TeV

CMS Collaboration

The production cross section of a top quark pair in association with a photon is measured in proton-proton collisions in the decay channel with two oppositely charged leptons (e$^\…
