Starting from the effective Lagrangian for QCD at high energy we calculate the lowest perturbative contributions to the potential of a relativistic nucleus and compare our results to those derived by Kovchegov [see Y.V. Kovchegov, Phys. Rev. D 55, 5445 (1997)]. The results differ already at order g(3) which can be traced to the fact that the meaning of the underlying gluon fields is different. (The effective gluon field we use is a gauge-invariant object.) Both approaches should therefore be seen as alternatives, the relative merits of which have to be judged by their phenomenological success. [S0556-2821(99)01715-4].
