摘要

我们考虑了带有π介子质量项的U（1）规范Skyrme模型的孤立子解。规范Skyrmions的存在域受到π介子质量值的限制。集中于拓扑度为1的解，我们发现与电磁场的耦合破坏了配置的对称性，Skyrmions携带电荷和磁通，并具有感应偶极磁矩。Skyrmions还具有角动量，该角动量以电荷为单位进行量化。规范Skyrmions的质量随着规范耦合的增加而单调减小。

Solitons in the Gauged Skyrme-Maxwell Model

We consider soliton solutions of the U(1) gauged Skyrme model with the pion mass term. The domain of existence of gauged Skyrmions is restricted from above by the value of the pion mass. Concentrating on the solutions of topological degree one, we find that coupling to the electromagnetic field breaks the symmetry of the configurations, the Skyrmions carrying both an electric charge and a magnetic flux, with an induced dipole magnetic moment. The Skyrmions also possess an angular momentum, which is quantized in the units of the electric charge. The mass of the gauged Skyrmions monotonically decreases with increase of the gauge coupling.
