Analytic calculation of color-Coulomb potential

We develop a calculation scheme in Coulomb and temporal gauge that respects gauge invariance and is most easily applied to the infrared asymptotic region of QCD. It resembles the Dyson-Schwinger equations of Euclidean quantum field theory in Landau gauge, but is three dimensional. A simple calculation yields a color-Coulomb potential that behaves at large R approximately like V₂₎ₔ₋ (R) R^1-0. 2 (d-1) for spatial dimension 13. This is a linearly rising potential plus a rather weak dependence on d.
