Neutrino decoherence in presence of strong gravitational fields

Understand

We explore the impact of strong gravitational fields on neutrino decoherence.

• To this aim, we employ the density matrix formalism to describe the propagation of neutrino wave packets in curved spacetime.
• By considering Gaussian wave packets, we determine the coherence proper time, neglecting the effect of matter outside the compact object.
• We show that strong gravitational fields nearby compact objects significantly influence neutrino coherence.
