Measurement of Zγ γ production in pp collisions at √s = 13 TeV with the ATLAS detector ATLAS Collaboration
Abstract
Cross-sections for the production of a Z boson in
association with two photons are measured in proton–proton
collisions at a centre-of-mass energy of 13 TeV. The data used
correspond to an integrated luminosity of 139 fb−1 recorded
by the ATLAS experiment during Run 2 of the LHC. The
measurements use the electron and muon decay channels of
the Z boson, and a fiducial phase-space region where the
photons are not radiated from the leptons. The integrated
Z(→ )γ γ cross-section is measured with a precision of
12% and differential cross-sections are measured as a function of six kinematic variables of the Zγ γ system. The data
are compared with predictions from MC event generators
which are accurate to up to next-to-leading order in QCD.
The cross-section measurements are used to set limits on the
coupling strengths of dimension-8 operators in the framework of an effective field theory.
