Static Color-Coulomb Force
Attilio Cucchieri, Daniel Zwanziger
Abstract
The static color-Coulomb interaction potential is calculated as the solution of a non-linear integral equation which arises in the Hamiltonian Coulomb gauge when the restriction to the interior of the Gribov horizon is implemented. The potential obtained is in qualitative agreement with expectations, being Coulombic with logarithmic corrections at short range, and confining at long range. The values obtained for the string tension and ΛMS are in semi-quantitative agreement with lattice Monte Carlo and phenomenological determinations.
