Description
The system of light quark and heavy antiquark source is studied in 1+1 QCD in the large N_C limit. The situation is demonstrated to be the two dimensional analogue of the problem in 3+1 QCD corresponding to the essentially nonlocal case of zero vacuum correlation length, which does not allow perturbative treatment. The modified Fock-Schwinger gauge condition is employed to derive the effective Dirac-type equation for the spectrum, which is proved to be equivalent to the 't Hooft equation in the limit of one heavy mass. The chiral condensate is shown to appear naturally in the given approach and to coincide with the convenient value.
