摘要:

具有特定U(1)对称势的标量场论包含被称为Q球的非拓扑孤子解。将U(1)提升为规范对称性会带来更复杂的带规范荷Q球(gauged Q-balls)情形。所得非线性微分方程组的孤子解具有显著不同的性质,例如存在最大可能尺寸和电荷。尽管存在这些差异,我们发现了一种关系,可从更易获得的全局Q球性质中推导出带规范荷Q球的性质(如半径、电荷和能量)。这些结果为理解带规范荷Q球提供了新的指引,也为Q球性质提供了简单准确的解析表征。

英文摘要:

Scalar field theories with particular U(1)-symmetric potentials contain non-topological soliton solutions called Q-balls. Promoting the U(1) to a gauge symmetry leads to the more complicated situation of gauged Q-balls. The soliton solutions to the resulting set of nonlinear differential equations have markedly different properties, such as a maximal possible size and charge. Despite these differences, we discover a relation that allows one to extract the properties of gauged Q-balls (such as the radius, charge, and energy) from the more easily obtained properties of global Q-balls. These results provide a new guide to understanding gauged Q-balls as well as providing simple and accurate analytical characterization of the Q-ball properties.
