Constraining off-shell production of axion-like particles with $Z\gamma$ and $WW$ differential cross-section measurements

This article describes a search for low-mass axionlike particles (ALPs) at the Large Hadron Collider (LHC). If ALPs were produced at the LHC via gluon-gluon fusion and decayed to bosons, the energy dependence of the measured diboson cross-sections would differ from the Standard Model expectation. Measurements of $WW$ and Z$γ$ differential cross sections by the ATLAS collaboration are interpreted to constrain ALP couplings to $W$-, $Z$-bosons and photons assuming gluon-gluon-fusion production
