More About QCD 3 On The World Sheet

In this article, we extend the world sheet treatment of planar QCD in 1+2 dimensions from an earlier work. The starting point is a field theory that lives on the world sheet, parametrized by the light cone variables. In the present work, we generalize and extend the variational approach introduced earlier to get sharper results. An iterative solution to the variational equations leads to a solitonic ground state, and fluctuations around this ground state signals formation of a string on the world sheet. At high energies, the asymptotic limit of the string trajectory is linear, with calculable corrections at lower energies.
