Abstract: We study -t Hooft-s integral equation determining the meson masses M n inmulticolor QCD 2. In this note we concentrate on developing an analytic method,and restrict our attention to the special case of quark massesm 1=m 2=g-\sqrt{\pi}. Among our results is systematic large-n expansion, andexact sum rules for M n. Although we explicitly discuss only the special case,the method applies to the general case of the quark masses, and we announcesome preliminary results for m 1=m 2.
