论文摘要
我们提出了沿约束激体溶液（约束的欧几里得方程的近似解决方案）沿$ \ rm su（2）$ \ rm su（2）$ yang-mills-higgs理论的构想（欧几里得方程的近似解决方案），以近似具有大量Pions的鼠模型中的天空解决方案。仪表场由于希格斯机制而获得非零质量的事实意味着，受约束的Instanton远离其中心的衰减，它通过Atiyah-Manton Construction生成的天空配置也是如此。这正是当包括斜向质量时，这正是真正的Skyrmion溶液在很大距离处的所需行为。
We present the idea of using the holonomy along a line of a constrained instanton solution (an approximate solution of the Euclidean equations of motion subject to a constraint) of an $\rm SU(2)$ Yang-Mills-Higgs theory to approximate the Skyrmion solution in a chiral model with massive pions. The fact that the gauge field acquires a nonzero mass due to the Higgs mechanism implies that a constrained instanton decays exponentially far from its center, and so does the Skyrmion configuration that it generates via the Atiyah-Manton construction. This is precisely the desired behavior at large distances for the true Skyrmion solutions when the pion mass is included.
