Charge screened non-topological solitons |
|
Abstract |
We show numerically the existence of non-topological soliton solutions in the system that consists of a massless complex scalar field coupled with a U(1) gauge field, and a complex Higgs scalar field with the Mexican hat potential which causes the spontaneous symmetry breaking. This system is a generalization of the Friedberg-Lee-Sirlin (FLS) model. The non-topological solitons obtained in this work are stationary and spherically symmetric localized solutions of the system. In the asymptotic far region, the U(1) symmetry is broken by the vacuum expectation value of the Higgs field, while in the central region, the massless scalar field yields charge distribution by its phase rotation. Immediately, the Higgs field and the gauge field yield counter charge which shield the source charge. Therefore, the all fields are localized in a finite region of the space. Implications of the solutions are discussed. |
