摘要：

Using an adiabatic approximation and the MIT bag model, we examine the effect of including a term in the charmonium wave function which contains one quantum of the lowest mode of the transverse gluon field in addition to the quark and antiquark. The amplitude of this term is calculated in perturbation theory, and its presence leads to a significant reduction in magnetic dipole transition rates with no corresponding reduction in electric dipole transitions. Although going in the right direction, the effect is not large enough to explain the discrepancy with the experimental M1 rates. © 1979.
