Neutrino oscillation processes in quantum field-theoretical approach

Abstract

It is shown that neutrino oscillation processes can be consistently described in the framework of quantum field theory. Namely, the oscillating electron survival probabilities in experiments with neutrino detection by charged-current and neutral-current interactions are calculated in the quantum field-theoretical approach to neutrino oscillations based on a modification of the Feynman propagator. The approach is most similar to the standard Feynman diagram technique in the momentum representation. It is found that the oscillating distance-dependent probabilities of detecting an electron in experiments with neutrino detection by charged-current and neutral-current interactions exactly coincide with the corresponding probabilities calculated in the standard approach.

arXiv commentFormula (37) has been brought to the form, which makes it evident that it coincides with the corresponding formula in the standard approach to neutrino oscillations. An erroneous statement right after this formula has been corrected. Corresponding amendments have been made in the abstract and in the conclusion
