Neutrino oscillations: deriving the plane-wave approximation in the wave-packet approach

Abstract

The plane-wave approximation is widely used in the practical calculations concerning neutrino oscillations. A simple derivation of this approximation starting from the neutrino wave-packet framework is presented.
