On the weak N-dependence of SO(N) and SU(N) gauge theories in 2+1 dimensions
We consider (continuum) mass ratios of the lightest ‘glueballs’ as a function of N for SO(N) and SU(N) lattice gauge theories in D=2+1. We observe that the leading large N correction is usually sufficient to describe the N-dependence of SO(N≥3) and SU(N≥2), within the errors of the numerical calcula...
