本文利用含复合场的手征Ward-Takahashi恒等式讨论了（2+1）维手征Gross-Neveu模型的费米子质量和束缚态的谱性质。在最低阶近似下,质量港与大N展开的结果一致。当手征对称是一种近似的对称性时,得到了轴矢流部分守恒。

Chiral Ward--Takahashi identities with composite fields are applied to investigate mass spectra in (2+1) dimensional chiral Gross-Neveu model. The fermion mass and bound state spectra are obtained, Which are in agreement with large-N expansion in the lowest approxim- ation. When the chiral symmetry is...
