论文摘要

在本文中,我们重新访问了$κ$成型的复杂标量字段的模型。我们发现,该模型具有十个保守的Noether指控,这些指控形成了换向因子,是(未拟合)庞加莱代数的代表。因此,该理论是相对论的,不会破坏洛伦兹的不变性。但是,升压的时空表示不是标准的,并且包含非本地翻译,对于正和负能量模式而言不同。因此,尽管颗粒和抗粒子的质量相等,但该理论以微妙的方式违反了CPT对称性。我们解释了为什么在我们的案例中,庞加莱对称和CPT等效的对等效性的Jost-Wight-Wightman-Greenberg定理失败了。最后,我们讨论了该理论及其可能的观察性特征的现象学后果。

In this paper we revisit the model of $κ$-deformed complex scalar field. We find that this model possesses ten conserved Noether charges that form, under commutators, a representation of (undeformed) Poincaré algebra. It follows that the theory is relativistic and does not break Lorentz invariance. However the spacetime representation of boosts is not standard, and contains a non-local translation, different for positive and negative energy modes. It then follows that although the masses of particles and anti-particles are equal, the theory violates CPT symmetry in a subtle way. We explain why the Jost-Wightman-Greenberg theorem of equivalence of the Poincaré symmetry and CPT fails in our case. Finally, we discuss the phenomenological consequences of the theory and its possible observational signatures.
