Title: Search for the decay η γ γ η

Abstract

Using a data sample of 1.31 × 109 J/ψ events collected with the BESIII detector, a search for η' → γγη via J/ψ → γη' is performed for the first time. No significant η' signal is observed in the γγη invariant mass spectrum, and the branching fraction of η' → γγη is determined to be less than 1.33 ×10–4 at the 90% confidence level.

abstractNote = {Using a data sample of 1.31 × 109 J/ψ events collected with the BESIII detector, a search for η' → γγη via J/ψ → γη' is performed for the first time. No significant η' signal is observed in the γγη invariant mass spectrum, and the branching fraction of η' → γγη is determined to be less than 1.33 ×10–4 at the 90% confidence level.},
