Coherence and Wave Packets in Neutrino Oscillations
arXiv:hep-ph/0302026 · doi:10.1023/B:FOPL.0000019651.53280.31
Abstract
General arguments in favor of the necessity of a wave packet description of neutrino oscillations are presented, drawing from analogies with other wave phenomena. We present a wave packet description of neutrino oscillations in stationary beams using the density matrix formalism. Recent claims of the necessity of an equal energy of different massive neutrinos are refuted.
