We investigate the weak decay of uniformly accelerated protons in the context of standard quantum field theory. Because the mean proper lifetime of a particle is a scalar, the same value for this observable must be obtained in the inertial and coaccelerated frames. We are only able to achieve this equality by considering the Fulling-Davies-Unruh effect. This reflects the fact that the Fulling-Davies-Unruh effect is mandatory for the consistency of quantum field theory.

We discuss the decay of accelerated protons and illustrate how the Fulling–Davies–Unruh effect is indeed mandatory to maintain the consistency of standard Quantum Field Theory. The confidence level
On the role of neutrino mixing in accelerated proton decay
The inverse beta decay of accelerated protons has been analyzed both in the laboratory frame (where the proton is accelerated) and in the comoving frame (where the proton is at rest and interacts
Semiclassical approach to the decay of protons in circular motion under the influence of gravitational fields
We investigate the possible decay of protons in geodesic circular motion around neutral compact objects. Weak and strong decay rates and the associated emitted powers are calculated using a
Is the Fulling–Davies–Unruh effect valid for the case of an atom coupled to quantum electromagnetic field?
We study, from the viewpoint of a co-accelerated observer, the average rate of change of atomic energy for an atom in uniform acceleration and coupled to quantum electromagnetic field at a thermal
Accelerated Multi-Level Atoms in an Electromagnetic Vacuum and Fulling–Davies–Unruh Effect
We consider, from the point of view of a coaccelerated frame, a uniformly accelerated multi-level atom in interaction with vacuum quantum electromagnetic fields in the multi-polar coupling scheme,
Matter-antimatter asymmetry and non-inertial effects
We investigate non-inertial effects on CP -violating processes using a model, based on the framework of quantum field theory in curved spacetimes, devised to account for the decay of accelerated
Unruh effect for mixing neutrinos
Recently, the inverse $\beta$-decay rate calculated with respect to uniformly accelerated observers (experiencing the Unruh thermal bath) was revisited. Concerns have been raised regarding the
Lifetime and decay of unstable particles in strong gravitational fields
We consider here the decay of unstable particles in geodesic circular motion around compact objects. For the neutron, in particular, strong and weak decay are calculated by means of a semiclassical
