Abstract
Quantum chromodynamics in two space-time dimensions with massless fermions is studied using the path-integral approach. Performing a non-Abelian chiral change of variables, the fermion determinant is solved exactly. Apart from a gluon mass term, it contains a Wess-Zumino anomaly term, also present in the solution of other two-dimensional models. Physical properties are discussed in terms of the resulting effective Lagrangian.
