Description

The effect of neutrino quantum decoherence has been studied actively in recent years (see [1-3] and references therein). In our present paper we consider the interaction with an arbitrary reservoir in thermodynamic equilibrium. We have found that within a fairly wide class of theoretical models the parameters of neutrino quantum decoherence are proportional to the neutrino decay rates into a massless particle and light neutrino state. The effect of neutrino quantum decoherence can play a role in neutrino evolution during supernova explosions and in other astrophysical environments.
