SU(Nc ) gauge theories for all Nc
Nuclear Physics B - Proceedings Supplements 53:1-3 (1997) 715-718
Abstract:
We show that SU (Nc) 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.COMMENTS ON THE HIGH Q**2 HERA ANOMALY
