We evaluate the decay rate of the uniformly accelerated proton. We obtain an analytic expression for the inverse beta decay process caused by the acceleration. We evaluate the decay rate both from the inertial frame and from the accelerated frame where we should consider thermal radiation by the Unruh effect. We explicitly check that the decay rates obtained in both frames coincide with each other. 
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
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
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
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
Neutrino mixing and general covariance in the inverse $β$ decay
We review recent developments on the role of neutrino mixing in the inverse $\beta$ decay of accelerated protons. We show that calculations in the inertial and comoving frames agree -- thus
Unlocking neutrino mysteries via the inverse β-decay
We discuss some recent results on neutrino physics in the context of the inverse β-decay of uniformly accelerated protons. Specifically, we compute the decay rate of the process p → n + e + + ν in
Source coupled to the massive scalar field orbiting a stellar object
In this work we analyze, using quantum field theory at tree level, the massive scalar radiation emitted by a source in uniform circular motion in Minkowski spacetime, assuming Newtonian gravitation,


Quantum field theory

Quantum Field Theory in Curved Space
Quantum field theory is described in the following non‐Minkowskian settings: Incomplete spaces (half‐spaces, slab spaces), spaces with moving boundaries, curved spaces (black holes). The problems of
