The Master Field of QCD2 and the 'T Hooft Equation
Abstract
We rewrite the action for QCD2 in the light cone gauge only in terms of a bilocal mesonic field. In this formalism the 1/N expansion can be done in a straightforward way by a saddle point technique that determines the master field to be identified with the vacuum expectation value of the bilocal field. Finally we show that the equation of motion for the fluctuations around the master field is identical with the 't Hooft meson equation.
