GREEN-FUNCTIONS IN THE COLOR FIELD OF A LARGE NUCLEUS

We compute the Green's functions for scalars, fermions, and vectors in the color field associated with the infinite momentum frame wave func tion of a large nucleus. Expectation values of this wave function can be computed by integrating over random orientations of the valence qua rk charge density. This relates the Green's functions to correlation f unctions of a two-dimensional, ultraviolet finite, field theory. We sh ow how one can compute the sea quark distribution functions and explic itly compute them in the kinematic range of transverse momenta, alpha( s)2mu2 << k(t)2 << mu2, where mu is the average color charge squared p er unit area. When m(quark)2 << mu2 approximately A1/3, the sea quark contribution to the infinite momentum frame wave function saturates at a value that is the same as that for massless sea quarks.
