论文摘要
对于轴突的四个维度,对非热的PT对称场理论提出了对质量生成的非扰动schwinger-dyson。 Schwinger-Dyson方程是针对具有通用耦合的模型得出的。在非富人的情况下,对标量质量有其他非扰动贡献。在简化的彩虹分析中,SD方程的解决方案是针对$ g $和$λ$的不同制度的。
A nonperturbative Schwinger-Dyson analysis of mass generation is presented for a non-Hermitian PT-symmetric field theory in four dimensions of an axion coupled to a Dirac fermion.The model is motivated by phenomenological considerations.The axion has a quartic self-coupling $λ$ and a Yukawa coupling $g$ to the fermion. The Schwinger-Dyson equations are derived for the model with generic couplings. In the non-Hermitian case there is an additional nonperturbative contribution to the scalar mass. In a simplified rainbow analysis the solutions for the SD equations, are given for different regimes of the couplings $g$ and $λ$.
