No significant deviation from the Standard Model is observed and upper limits are placed on the production cross-section times branching ratio to two photons as a function of the resonance mass. © 2021 The Author(s)enHadronLeptonStandard ModelArtículoAttribution 4.0 International CC BY 4.0 Deed10.1016/j.physletb.2021.136651
