论文摘要

由于peccei-quinn(PQ)对称性必须异常地解决强大的CP拼图,因此在此对称性下,一些有色和手性的费米子必须非琐事地转化。但是,当对SM费用充电(如PQ或DFSZ模型中)时,这种对称性最终与SM全局对称性,Baryon(B)和Lepton(L)数字纠缠在一起。这提出了本文解决的几个问题。首先,分析了与某些明确的B和/或L违反效果的轴轴模型的兼容性,包括由Seesaw机制,Electroweak Instanton Itsportions或显式B和L违反有效的操作员产生的兼容。其次,量化了可以同时存在多少这些效果,以及如果引入过多的轴突质量和真空对齐的后果。最后,确定了大量的B和/或L违反相互作用而没有影响轴突现象学的相互作用,例如,在DFSZ环境中,I型和II型SEESAW机制的各种实现。

Because the Peccei-Quinn (PQ) symmetry has to be anomalous to solve the strong CP puzzle, some colored and chiral fermions have to transform non-trivially under this symmetry. But when the SM fermions are charged, as in the PQ or DFSZ models, this symmetry ends up entangled with the SM global symmetries, baryon (B) and lepton (L) numbers. This raises several questions addressed in this paper. First, the compatibility of axion models with some explicit B and/or L violating effects is analyzed, including those arising from seesaw mechanisms, electroweak instanton interactions, or explicit B and L violating effective operators. Second, how many of these effects can be simultaneously present is quantified, along with the consequences for the axion mass and vacuum alignment if too many of them are introduced. Finally, large classes of B and/or L violating interactions without impact on axion phenomenology are identified, like for example the various implementations of the type I and II seesaw mechanisms in the DFSZ context.
