摘要：

We derive a covariant formalism to describe D-wave quarkonium production and annihilation decays in the context of nonrelativistic potential models. We apply it to evaluate the decay rates for such processes as Z0 --> 1D2 + gamma, 3D(J) + gamma (where J = 1,2,3) and other previously uncalculated precesses. Despite the appearance of relatively large numerical coefficients, we find no case in which D-wave states (followed by radiative decays) make any significant contributions to inclusive 3S1 quarkonium production.
