Abstract

The evolution of the entangled muon-neutrino system emerging from charged pion decay is explored both in vacuum and in matter. The study is based on a Weisskopf-Wigner type wave-packet description. Explicit formulas are derived displaying modulation and attenuation of the oscillations due to additional time scales characterizing the production process. The case of neutrinos disentangled due to the detection of the muon is also considered.
