Abstract

Using a data sample containing $1.06 \times 10^{8}$ $ψ^{'}$ events collected with the BESIII detector at the BEPCII electron-positron collider, we search for a light exotic particle $X$ in the process $ψ^{'} \to π^{+} π^{-} J / ψ$ , $J / ψ \to γ X$ , $X \to μ^{+} μ^{-}$ . This light particle $X$ could be a Higgs-like boson $A^{0}$ , a spin-1 $U$ boson, or a pseudoscalar sgoldstino particle. In this analysis, we find no evidence for any $μ^{+} μ^{-}$ mass peak between the mass threshold and $3.0 GeV / c^{2}$ . We set 90%-confidence-level upper limits on the product-branching fractions for $J / ψ \to γ A^{0}$ , $A^{0} \to μ^{+} μ^{-}$ which range from $4 \times 10^{- 7}$ to $2.1 \times 10^{- 5}$ , depending on the mass of $A^{0}$ , for $M (A^{0}) < 3.0 GeV / c^{2}$ . Only one event is seen in the mass region below $255 MeV / c^{2}$ , and this has a $μ^{+} μ^{-}$ mass of $213.3 MeV / c^{2}$ and the product-branching-fraction upper limit $5 \times 10^{- 7}$ .
