Measurement of the $Z(\to {\ell }^{+}{\ell }^{-})\gamma$ production cross-section in $pp$ collisions at $\sqrt{s}=13$ TeV with the ATLAS detector

ATLAS Collaboration

The production of a prompt photon in association with a $Z$ boson is studied in proton-proton collisions at a centre-of-mass energy $\sqrt{s}=$ 13 TeV. The analysis uses a data sa…
