Sensitivity of the FCC-ee to decay of an axion-like particle into two photons

Abstract The decay of the Z boson into axion-like particles (ALP) at the Z-pole run of the proposed CERN FCC-ee collider is investigated. We perform a detailed study of final states with three photons or with a single photon and missing energy, yielding an evaluation of the accessible values of the...
