EVIDENCE FOR DIRECT PHOTONS FROM QUARKS IN ELECTRON-POSITRON ANNIHILATION

Abstract:

Hadronic events from e+e--annihilations with a high energy isolated photon have been investigated at C.M. energies between 14 GeV and 44 GeV. A forward-backward asymmetry Aγ of the positively charged jet with respect to the incident positron direction has been found:Aγγ=-0.32±0.07, providing evidence for photon bremsstrahlung from quarks. The forward-backward asymmetry of all hadronic events at C.M. energies between 30 GeV and 36 GeV has been measured. The value, corrected for the limited pol...
