The interactions of 420—500 Me V/c K− in the 11T hydrogen bubble chamber HYBUC have been used to produce a sample of 120,000 σ± decays in flight1,2. We describe here how these decays were used to investigate the effects of longitudinal accelerations between 0.5 and 5.0 × 1015g on particle lifetimes. Any observed effect of acceleration on lifetime would indicate that the Lorentz transformation and/or the dynamics of particle decay is sensitive to acceleration. These data suggest that… 
Acceleration effects on atomic clocks
We consider a free massive particle inside a box that is dragged by Rindler observers. Admitting that the particle obeys the Klein–Gordon equation, we find the frequencies of the stationary states of

Abstract Decay laws of unstable quantum systems, which move with constant linear momentum in the laboratory reference frame and exhibit oscillating decay rate, are analyzed over intermediate times.
Moving Unstable Particles and Special Relativity
In Poincare-Wigner-Dirac theory of relativistic interactions, boosts are dynamical. This means that, just like time translations, boost transformations have a nontrivial effect on internal variables
Relativistic Quantum Dynamics: A non-traditional perspective on space, time, particles, fields, and action-at-a-distance
This book is an attempt to build a consistent relativistic quantum theory of interacting particles. In the first part of the book "Quantum electrodynamics" we follow rather traditional approach to
