The real part of Fermion determinant and Fermion propagator are generalized with m substituted by momentum dependent Fermion self energy inverse for Dirac operator with dynamical chiral symmetry breaking caused by momentum dependent Fermion self energy ∑(k~2).
考虑到动力学手征对称性破缺效应,将含有硬费米子质量项的费米子行列式与真空凝聚推广为含有动量相关的费米子自能项的情况;并且推广了Schwinger proper-time方法,使之能够计算含有动量相关的费米子自能的费米子传播子;探讨了4维可重整化的量子场论中费米子在路径积分中的贡献。
The concept of chirality in atomic nuclei was first proposed in 1997, and since then many efforts have been made to understand chiral symmetry and its spontaneous breaking in atomic nuclei.
