Abstract: (APS)

The cross section for e+e−→ρπ has been measured by the BES detector at BEPC at center-of-mass energies covering a 40 MeV interval spanning the Jψ resonance. The data are used to search for the vector gluonium state hypothesized by Brodsky, Lepage, and Tuan as an explanation of the ρπ puzzle in charmonium physics. The shape of the ρπ cross section is compatible with that of the total hadronic cross section. No distortions indicating the presence of a vector glueball are seen.
