Working in four-dimensional quantum chromodynamics, we solve exactly the renormalized gluon ladder at t = 0. This approximation is obtained by reordering the perturbation expansion of the Bethe-Salpeter kernel using the renormalization group. The resulting amplitude has an accumulation of Regge poles at j = +1 in any gauge with gauge-fixing term -(2..cap alpha..)/sup -1/(partial-arrow-right x A)/sup 2/. The existence of this singularity depends only on the short-distance behavior of the forces in the t channel as given by the renormalization group. Further, this singularity couples to hadrons, and is a natural candidate for the bare Pomeron.
