From the observed yield and properties of isolated energetic photons in the reaction e⁺e^-→Z⁰→hadrons+γ measured with the OPAL detector at LEP, evidence for final state radiation from primary quarks is obtained. Combined with the measurement of the total hadronic width of the Z⁰, the observed rate allows the extraction of the electroweak coupling constants of up and down type quarks: ν_{1 3}² + a_{1 3}² = 1.24±0.47 and ν_{2 3}² + a_{2 3}² = 1.72±0.70 No evidence for additional photon production from anomalous decays of the Z⁰ or from decays of new particles is found. This measurement limits the contribution to the total Z⁰ width from such sources to be less than 8.2 MeV at the 95% confidence level.

N2 - From the observed yield and properties of isolated energetic photons in the reaction e+e-→Z0→hadrons+γ measured with the OPAL detector at LEP, evidence for final state radiation from primary quarks is obtained. Combined with the measurement of the total hadronic width of the Z0, the observed rate allows the extraction of the electroweak coupling constants of up and down type quarks: ν 1 32 + a 1 32 = 1.24±0.47 and ν 2 32 + a 2 32 = 1.72±0.70 No evidence for additional photon production from anomalous decays of the Z0 or from decays of new particles is found. This measurement limits the contribution to the total Z0 width from such sources to be less than 8.2 MeV at the 95% confidence level.
