论文摘要
我们研究了两分量的Fridberg-Lee-Sirlin-Maxwell模型，以及在具有六型电势的单组分标量模型中，在两分量Fridberg-lee-Sirlin-Maxwell模型中研究球形对称$ u（1）$测量的Q-Ball配置的规范能量量。我们评估相应的剪切力和压力的分布，并研究这些溶液的稳定性标准。结果表明，静电排斥可能会破坏$ u（1）$衡量的Q-balls。但是，在具有长期范围的真实标量组件的Fridberg-Lee-Sirlin-Maxwell模型的限制情况下，计量Q-Balls始终保持稳定。
We study the canonical energy-momentum tensor of the spherically symmetric $U(1)$ gauged Q-ball configurations in the two-component Fridberg-Lee-Sirlin-Maxwell model, and in the one-component scalar model with a sixtic potential. We evaluate the distributions of the corresponding shear forces and pressure and study the stability criteria for these solutions. It is shown that the electrostatic repulsion may destabilize the $U(1)$ gauged Q-balls. However, in the limiting case of the Fridberg-Lee-Sirlin-Maxwell model with a long ranged real scalar component, the gauged Q-balls always remain stable.
