| Description: | Lepton number violation decay ω → π+π+e−e− + c.c. is searched for via J/ψ → ωη using a data sample of (1.0087 ± 0.0044) × 1010 J/ψ events collected via the BESIII detector at the BEPCII collider. No significant signal is observed, and the upper limit on the branching fraction of ω → π+π+e−e− + c.c. at the 90% confidence level is determined for the first time to be 2.8 × 10−6. |
