Resumen

We search for an axion-like particle (ALP) a through the process ψ(3686)→π⁺π⁻J/ψ, J/ψ→γa, a→γγ in a data sample of (2.71±0.01)×10⁹ ψ(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/ψ→γa and the ALP-photon coupling constant g_aγγ are set at 95% confidence level in the mass range of 0.165≤m_a≤2.84GeV/c². The limits on B(J/ψ→γa) range from 8.3×10⁻⁸ to 1.8×10⁻⁶ over the search region, and the constraints on the ALP-photon coupling are the most stringent to date for 0.165≤m_a≤1.468GeV/c².
