Two-dimensional Yang-Mills theory in the leading 1/N expansion revisited
We obtain a formal solution of an integral equation for $q\bar q$ bound states, depending on a parameter \eta which interpolates between 't Hooft's expression for its spectrum for a particular value of the ratio of the coupling constant to the quark mass. The spectrum turns out to be in qu...
