Abstract:
Neutrino oscillations are often treated using the external wave packet model, in which the neutrino source and detector are replaced by rigid external wavepackets which neither spread nor entangle. However neutrino oscillations are expected to damp as a result of the entanglement of the source and detector with the environment. A derivation of this damping therefore requires a fully dynamical treatment of the source and detector. We construct a model which does this and use it study neutrino oscillations in the vacuum.
