Asymptotic properties of mass spectrum in 't Hooft's model of mesons

Abstract

We study 't Hooft's equation for bound states in 2d multicolor QCD. We consider the case of quarks with equal masses. We derive asymptotic expansions for the spectrum of mesons in different regimes and study their properties.
