Probing the Quantum Interference between Singly and Doubly Resonant Top-Quark Production in pp Collisions at s =13 TeV with the ATLAS Detector

This Letter presents a normalized differential cross-section measurement in a fiducial phase-space region where interference effects between top-quark pair production and associated production of a single top quark with a W boson and a b-quark are significant. Events with exactly two leptons (ee, μμ...
