标题： The Skyrmion limit of the Nambu--Jona-Lasinio soliton

摘要： 同位标量介子（$\sigma$和$\omega$）在NJL孤子中的特殊作用被讨论。 当假设与零总自旋相容的最一般假设时，得到了稳定的孤子解。 这些解与纯赝标量Skyrme型模型的孤子解进行了比较，该模型通过梯度展开和无限重（轴向）矢量介子极限与NJL模型相关。 显示英文摘要

摘要： The special role of the isoscalar mesons ($\sigma$ and $\omega$) in the NJL soliton is discussed. Stable soliton solutions are obtained when the most general ansatz compatible with vanishing grand spin is assumed. These solutions are compared to soliton solutions of a purely pseudoscalar Skyrme type model which is related to the NJL model by a gradient expansion and the limit of infinitely heavy (axial-) vector mesons.
