SU(Nc) gauge theories for all Nc.
Abstract
We show that SU(N c) gauge theories in 2+1 dimensions are close to Nc = ∞ for Nc ≥ 2. The dimensionful coupling, g2, is proportional to 1/ Nc, at large Nc, confirming the usual diagram-based expectation. Preliminary calculations in 3+1 dimensions indicate that the same is true there.
