Search for the rare decays J /ψ → Ds-ρ+ and J /ψ → D ̄ 0 K ̄ *0 SEARCH for the RARE DECAYS ⋯ M. ABLIKIM et al.
A search for the rare decays of J/ψ→Ds-ρ++c.c. and J/ψ→D̄0K̄*0+c.c. is performed with a data sample of 225.3-million J/ψ events collected with the Beijing Spectrometer III detector. No evident signal is observed. Upper limits on the branching fractions are determined to be B(J/ψ→Ds-ρ++c.c.)<1.3×10-5 and B(J/ψ→D̄0K̄*0+c.c.)<2.5×10-6 at the 90% confidence level. © 2014 American Physical Society.
