Abstract

The defect-type solutions of a deformed O(2N+1) linear sigma model with a real and N complex fields in (1+1)-dimensional Minkowski spacetime are studied. All the solutions are analytically found for the N=2 case. Two types of solitons have been determined: (a) Simple solutions formed by a topological kink with or without the presence of a Q-ball. (b) Composite solutions. They are constituted by some one-parameter families of solutions which can be understood as a non-linear combination of simple solutions. The properties of all of those solutions and the analysis of their linear stability, as well as decay channels, are discussed.
