Abstract/OtherAbstract:
|
Using 586 pb^{-1} of e^{+}e^{-} collision data at E_{c.m.}=4170 MeV, produced at the Cornell Electron Storage Ring collider and collected with the CLEO-c detector, we observe the process e^{+}e^{-}→π^{+}π^{-}h_{c}(1P). We measure its cross section to be 15.6±2.3±1.9±3.0 pb, where the third error is due to the external uncertainty on the branching fraction of ψ(2S)→π^{0}h_{c}(1P), which we use for normalization. We also find evidence for e^{+}e^{-}→ηh_{c}(1P) at 4170 MeV at the 3σ level and see hints of a rise in the e^{+}e^{-}→π^{+}π^{-}h_{c}(1P) cross section at 4260 MeV. |
