Abstract
The study of the decay of an accelerated proton recently provided a “theoretical proof” of the Unruh effect. On the basis of general covariance of Quantum Field Theory, indeed, it was found that the decay rates in the inertial and comoving frames do coincide only when the thermal nature of the accelerated vacuum is taken into account. Such an analysis was then extended to the case with mixed neutrinos. In this paper, we show that, by further embedding neutrino oscillations in the above framework, the requirement of general covariance necessarily entails the use of flavor neutrinos as asymptotic states, as well as the occurrence of neutrino oscillations in the Unruh thermal bath.
Highlights
General covariance has been advocated to exhibit that the internal consistency of quantum field theory (QFT) unavoidably requires the existence of the Unruh effect, known as Fulling-Davies-Unruh effect [1– 3]
In this Letter we show that, due to the occurrence of neutrino oscillations in the problem at hand, general covariance leads to the conclusion that flavor eigenstates are fundamental and neutrinos belonging to the Unruh radiation must oscillate
In this Letter, we have extended the formalism firstly introduced in Refs. [5] and developed in Refs. [10–12] to the case in which neutrino oscillations are taken into account
