Search for high-mass Zγ resonances in e+e−γ and μ + μ −γ final states in proton-proton collisions at √s=8 and 13 TeV

This paper describes the search for a high-mass narrow-width scalar particle decaying into a Z boson and a photon. The analysis is performed using proton-proton collision data recorded with the CMS detector at the LHC at center-of-mass energies of 8 and 13 TeV, corresponding to integrated luminos...
