Abstract

Using e+e- collision data corresponding to 5.88×106γ(3S) [25.9×106ψ(2S)] decays and acquired by the CLEO III [CLEO-c] detectors operating at the Cornell Electron Storage Ring, we study the single-pion transitions from γ(3S)[ψ(2S)] to the respective spin-singlet states hb[c]. Utilizing only the momentum of suitably selected transition-π0 candidates, we obtain the upper limit B(γ(3S)→π0h b)<1.2×10-3 at 90% confidence level, and measure B(ψ(2S)→π0hc)=(9.0±1.5±1.3) ×10-4. Signal sensitivities are enhanced by excluding very asymmetric π0→γγ candidates.
