The phases and mass spectrum with quantum kinks of the Z(4) symmetric φ _{2}^{4} theory
Abstract
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.
