Schwinger-Dyson equations and mass generation for an axion theory with a PT symmetric Yukawa fermion interaction
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 couplin...
