  We show that the gluon distribution function for very large nuclei may be
computed for small transverse momentum as correlation functions of an
ultraviolet finite two dimensional Euclidean field theory. This computation is
valid to all orders in the density of partons per unit area, but to lowest
order in $\alpha_s$. The gluon distribution function is proportional to $1/x$,
and the effect of the finite density of partons is to modify the dependence on
transverse momentum for small transverse momentum.
