Abstract

(1+1)-dimensional QCD (QCD₁₊₁) in the limit of a large number of flavors N_F and a large number of colors N_C is examined in the small N_F/N_C regime. Using perturbation theory in N_F/N_C, stringent results for the leading behavior of the spectrum departing from N_F/N_C=0 are obtained. These results provide benchmarks in the light of which previous truncated treatments of QCD₁₊₁ at large N_F and N_C are critically reconsidered.
