尝试将电磁相互作用纳入洛伦兹不变量但违反 CPT 的非局域模型中，并具有粒子-反粒子质量分裂，这被视为改进的 QED。规范不变性由施温格不可积相位因子维持，但电磁相互作用破坏了 C、CP 和 CPT 对称性。讨论了当前 CPT 破坏方案对电磁跃迁和粒子-反粒子对生成的影响。像这封信中所建议的那样的 CPT 违反可能会为重子不对称性的分析开辟一条新途径，因为一些萨哈罗夫约束预计将被修改。
An attempt is made to incorporate the electromagnetic interaction in a Lorentz invariant but CPT violating non-local model with particle–antiparticle mass splitting, which is regarded as a modified QED. The gauge invariance is maintained by the Schwinger non-integrable phase factor but the electromagnetic interaction breaks C, CP and CPT symmetries. Implications of the present CPT breaking scheme on the electromagnetic transitions and particle–antiparticle pair creation are discussed. The CPT violation such as the one suggested in this Letter may open a new path to the analysis of baryon asymmetry since some of the Sakharov constraints are expected to be modified.
