摘要：

We search for an axion-like particle (ALP) a through the process psi (3686) ->pi+pi-J/psi, J/psi -> gamma a, a -> gamma gamma in a data sample of (2.71 + 0.01) x 109 psi (3686) events collected by the BESIII detector. No significant ALP signal is observed over the expected background, and the upper limits on the branching fraction of the decay J/psi -> gamma a and the ALP-photon coupling constant ga gamma gamma are set at 95% confidence level in the mass range of 0.165 < ma < 2.84 GeV/c2. The limits on B(J/psi -> gamma a) range from 8.3 x 10-8 to 1.8 x 10-6 over the search region, and the constraints on the ALP-photon coupling are the most stringent to date for 0.165 < ma < 1.468 GeV/c2.
