The abstract, sentence by sentence

arXiv listing abstract v1. Results and the main claim are underlined; .

The standard theory of neutrino oscillations is reviewed, highlighting the main assumptions: the definition of the flavor states, the equal-momentum assumption and the time = distance assumption. It is shown that the standard flavor states are correct approximations of the states that describe neutrinos in oscillation experiments. The equal-momentum assumption is shown to be unnecessary for the derivation of the oscillation probability. The time = distance assumption derives from the wave-packet character of the propagating neutrinos. We present a simple quantum-mechanical wave-packet model which allows us to describe the coherence and localization of neutrino oscillations.

  • Following the procedure developed in Refs. [ref] , by considering one only one space dimension, a neutrino with definite flavor, propagating along the $x$ direction. can be described by the state: [equation] where the $U_α,j$ denotes the corresponding element of the mixing matrix, $|ν_j⟩$ is the mass eigenstate with mass $m_j$, and $ψ_j(x,t)$ is its wave function.

  • A review of the oscillation mechanism in full detail can be found for instance in [ref] ; here, for the purposes we're interested in, let us consider the oscillation in vacuum of two neutrino species: [equation] This expression describes the probability that a neutrino is detected with flavour $β$ after a flight of length $L$ if it had flavour $α$ at the moment of production and it carries an energy $E$.
