| dc.description.abstract | Based on (10087±44)×106 J/ψ events collected with the BESIII detector at BEPCII, the double Dalitz decay η′→e+e-e+e-is observed for the first time via the J/ψ→γη′ decay process. The significance is found to be 5.7σ with systematic uncertainties taken into consideration. Its branching fraction is determined to be B(η′→e+e-e+e-)=(4.5±1.0(stat)±0.5(sys))×10-6. © 2022 authors.
