Using data collected with the CLEO II detector at the Cornell Electron Storage Ring, we determine the ratio Rchrg for the mean charged multiplicity observed in Y(1S)→ggγ events, 〈n±gluon〉, to the mean charged multiplicity observed in e+e-→qq̄γ events, 〈n±quark〉. We find Rchrg≡〈n±gluon〉/〈n±quark〉=1.04 ±0.02(stat)±0.05(syst) for jet-jet masses less than 7 GeV. |
