We consider the @x model in a l/ 4; expansion in six-dimensional Euclidean spacetime. Using the path-integral formalism and the method of stationary phase we show the existence of two phases in the model: with broken U(N) symmetry and with O(N) maintained. In both phases the massless q fields acquir
