In a recent paper [Eur. Phys. J. C 80, 68 (2020)], a definition of oscillating neutrino states in quantum field theory was proposed. We show that such definition can be derived as a particular case of the Blasone–Vitiello approach, when mass vacuum is chosen as the physical vacuum. We discuss some problems of such an approach, which appears to be mathematically inconsistent and physically not acceptable.

量子场论中中微子振荡态的注解

在最近的一篇论文中 [Eur. 物理。J. C 80, 68 (2020)]，提出了量子场论中振荡中微子态的定义。We show that such definition can be derived as a particular case of the Blasone–Vitiello approach, when mass vacuum is chosen as the physical vacuum. 我们讨论了这种方法的一些问题，这些问题似乎在数学上不一致并且在物理上是不可接受的。
