We study how the decay properties of particles are changed by acceleration. It is shown that under the influence of acceleration (1) the lifetime of particles is modified and (2) new processes (such as the decay of the proton) become possible. This is illustrated by considering scalar models for the decay of muons, pions, and protons. We discuss the close conceptual relation between these processes and the Unruh effect.

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
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
Unruh effect and particle decay
We review the study of the inverse β-decay of uniformly accelerated protons in the context of neutrino flavor mixing. Letting ourselves be guided by some core theoretical principles, such as the
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
Review of some recent work on acceleration radiation
Some developments in quantum field theory in accelerated frames that may not have got the attention they deserve are reviewed here. They concern (1) elementary particles as radiating accelerated
On CP violation and relativistic non-inertial effects
This dissertation investigates the impact that non-inertial effects predicted by quantum field theory in curved spacetimes have on the phenomenon of CP violation by analyzing the relative rate of CP
Flavor neutrinos as unstable particles
In this paper we review flavor-energy uncertainty relations for neutrino oscillations in quantum field theory, putting in evidence the analogy with the case of unstable particles. Our study reveals
Can a charged decaying particle serve as an ideal clock in the presence of a magnetic field
We investigate a model of a supposedly ideal clock based on the decay rate of a charged particle in circular motion in a constant magnetic field. We show that the time measured by an ideal clock
Remarks on the Unruh effect with mixed neutrinos
We discuss some recent results on the inverse β-decay of an accelerated proton in the presence of neutrino mixing. By comparing different approaches, we conclude that a consistent treatment
