Quantum field-theoretical description of neutrino and neutral kaon oscillations

Abstract

It is shown that the neutrino and neutral kaon oscillation processes can be consistently described in quantum field theory using only the mass eigenstates of neutrinos and neutral kaons. The distance-dependent and time-dependent parts of the amplitudes of these processes are calculated and the results turn out to be in accord with those of the standard quantum mechanical description of these processes based on the notion of neutrino flavor states and neutral kaon states with definite strangeness. However, the physical picture of the phenomena changes radically: now there are no oscillations of flavor or definite strangeness states, but, instead of it, there is an interference of amplitudes due to different virtual mass eigenstates.
