论文摘要
我们讨论了在有效的理论的情况下，讨论了费米和伪赛场（类似轴突样颗粒（ALP））的动态质量产生。我们讨论了Hermitian和非柔米的Yukawa相互作用，这些相互作用是在某些有效的领域理论中的辐射（异常）小型中微子群众的某些情况下的动机。后者包含无菌中微子和阿尔卑斯山之间的横向对称性破坏Yukawa的相互作用。我们表明，对于冬宫的育川相互作用，没有（伪）标量的动力学质量产生，但是有Fermion动力学生成，但前提是增加了一个裸露的（伪）标量质量。这种情况与反武士Yukawa模型相反：存在（伪）标量动力学质量产生，但没有费米昂动态质量产生。在存在其他有吸引力的四效相互作用的情况下，在适当的条件下，这些模型中可能会发生动力学费用质量产生。
We discuss dynamical mass generation for fermions and pseudoscalar fields (axion-like particles (ALP)), in the context of effective theories containing Yukawa type interactions between the fermions and ALPs. We discuss both Hermitian and non-Hermitian Yukawa interactions, which are motivated in the context of some scenarios for radiative (anomalous) Majorana sterile neutrino masses in some effective field theories. The latter contain shift-symmetry breaking Yukawa interactions between sterile neutrinos and ALPs. We show that, for a Hermitian Yukawa interaction, there is no (pseudo)scalar dynamical mass generation, but there is fermion dynamical mass generation, provided one adds a bare (pseudo)scalar mass. The situation is opposite for an anti-Hermitian Yukawa model: there is (pseudo)scalar dynamical mass generation, but no fermion dynamical mass generation.In the presence of additional attractive four-fermion interactions, dynamical fermion mass generation can occur in these models, under appropriate conditions and range of their couplings.
