SU(N) gauge theories in 2+1 dimensions: Further results

Journal article

We calculate the string tension and part of the mass spectrum of SU(4) and SU(6) gauge theories in 2+1 dimensions using lattice techniques. We combine these new results with older results for Nc=2, . . . ,5 so as to obtain more accurate extrapolations to Nc=∞. The qualitative conclusions of the earlier work are unchanged: SU(Nc∞) theories in 2+1 dimensions are linearly confining as N c→∞ the limit is achieved by keeping g2Nc fixed; SU(3), and even SU(2), are "close" to SU(∞). We obtain more convincing evidence than before that the leading large-Nc correction is O(1/N c2). We look for the multiplication of states that one expects in simple flux loop models of glueballs, but find no evidence for this. © 2002 The American Physical Society.
