Neutrinos, mixed bosons, Quantum Reference Frames and entanglement

Abstract

We discuss the relevance of quantum reference frames in the description of mixed particle states. We show that the notion of rest frame for mixed particles, which is classically ill-defined, can be introduced in the context of quantum frames. We discuss the possible phenomenological implications, displaying a new form of framedependent entanglement that characterizes reactions involving mixed particles.
