QCD_2 in the axial gauge revisited

. The ’t Hooft model for the two-dimensional QCD in the limit of infinite number of colours is studied in the axial gauge. The mass-gap and the bound-state equations are derived using the two consequent Bogoliubov-like transformations. Chiral properties of the model are studied in the Hamiltonian and matrix ap- proaches to the latter. Special attention is payed to the explicit pionic solution of the bound-state equation.
