Description

We present detailed results on the calculation of the decay of a heavy 1-- quarkonium state into a photon and two vector gluons in Born approximation. We tabulate and graph the formulas for the Dalitz plots, the photon energy spectrum, the angular correlations between the γ-event plane and the beam direction, and for the linear polarization asymmetry of the produced photon. We compare the QCD results with a model where the heavy 1-- quarkonium state decays into a photon and two colored, scalar gluons. (orig.)
