The running gauge coupling constant remains unaltered and the string tension in the high energy limit vanishes asymptotically. Using 1/N techinique the theory can be explicitly analytically computable with cofinement built in . Spontaneous chiral symmetry breakdown along with its Goldstone is exhibited.4 pages, REVtexHigh Energy Physics - PhenomenologyHigh Energy Physics - Theorytext
