摘要
基于规范场的Faddeev-Niemi分解和随机-有序假设,由SU(2)杨-米尔斯规范理论推导出一个含有附加常数的有效对偶阿贝尔-黑格斯模型.推导过程显示,黑格斯复标量φ可用来描述有效真空磁介质,并预言单极质量由n场的梯度涨落所决定;引入夸克源之后还预言麻省口袋模型中的真空常数正比于单极质量的四次方.通过求解对偶阿贝尔-黑格斯模型方程对杨-米尔斯理论的对偶超导机制进行了探讨.
A dual Abelian-Higgs model with additional constant is derived from the SU（2） Yang-Mills theory based on the Faddeev-Niemi decomposition and random-order assumptions. The derivation implies that the vacuum magnetic medium can be parameterized by the Higgs complex scalar φ, and the monopole mass is determined by the gradient fluctuation of an isovector n; when the quark sources is introduced, the vacuum constant in the MIT bag model is proportional to the quartic of the monopole mass. The dual superconductor mechanism of the theory is discussed via solving the dual Abelian-Higgs model.
