Affine Toda model coupled to matter and the string tension in 2D QCD

The (Formula presented) affine Toda model coupled to matter is shown to describe various features, such as the spectrum and string tension, of the low-energy effective Lagrangian of two-dimensional QCD (one flavor and N colors). The corresponding string tension is computed when the dynamical quarks are in the fundamental representation of (Formula presented) and in the adjoint representation of (Formula presented) © 2002 The American Physical Society.
