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