Abstract: (Elsevier)
We study the Z(4) symmetric φ 2 4 theory with N complex scalar fields, in the large- N limit, taking into account its fully quantized kinks. The complete phase diagram is obtained from a detailed study of the effective potential. Kink correlation functions are obtained in the leading order in 1/ N . The whole mass spectrum is evaluated in each phase. This includes explicitly the kink masses, whenever the symmetry is broken.
