Abstrakt
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.
