abstract = "We search for J/ψ radiative decays into a weakly interacting neutral particle, namely an invisible particle, using the J/ψ produced through the process ψ(3686)→π+π-J/ψ in a data sample of (448.1±2.9)×106 ψ(3686) decays collected by the BESIII detector at BEPCII. No significant signal is observed. Using a modified frequentist method, upper limits on the branching fractions are set under different assumptions of invisible particle masses up to 12 GeV/c2. The upper limit corresponding to an invisible particle with zero mass is 7.0×10-7 at the 90% confidence level.",

N2 - We search for J/ψ radiative decays into a weakly interacting neutral particle, namely an invisible particle, using the J/ψ produced through the process ψ(3686)→π+π-J/ψ in a data sample of (448.1±2.9)×106 ψ(3686) decays collected by the BESIII detector at BEPCII. No significant signal is observed. Using a modified frequentist method, upper limits on the branching fractions are set under different assumptions of invisible particle masses up to 12 GeV/c2. The upper limit corresponding to an invisible particle with zero mass is 7.0×10-7 at the 90% confidence level.
