dc.description.abstractWe search for a light Higgs boson A0 in the fully reconstructed decay chain of J/?›?A0, A0›µ+µ- using (225.0±2.8)×106 J/? events collected by the BESIII experiment. The A0 is a hypothetical CP-odd light Higgs boson predicted by many extensions of the Standard Model including two spin-0 doublets plus an extra singlet. We find no evidence for A0 production and set 90% confidence-level upper limits on the product branching fraction B(J/?›?A0)×B(A0›µ+µ-) in the range of (2.8-495.3)×10-8 for 0.212?mA0?3.0 GeV/c2. The new limits are 5 times below our previous results, and the nature of the A0 is constrained to be mostly singlet.en_US
