Abstract:

It is shown that the relativistic gluon corrections for the states with j ≠0 are consistently included in the instantaneous ladder BS equation but the higher-order kernels may contribute to the ground states with j=0. The retardation correction is examined. The relativistic effect is shown to be essential to get the reasonable value for M(η_c).
