Cosmological gravitational particle production and its implications for cosmological relics
Cosmological gravitational particle production (CGPP) is the creation of particles in an
expanding universe due solely to their gravitational interaction. These particles can play an …

A perturbation theory for the Coulomb phase infrared-divergence
L Lippstreu - arxiv preprint arxiv:2312.08455, 2023 - arxiv.org
We construct a perturbation theory which we conjecture to be free of the Coulomb-phase
infrared divergence. This perturbation theory is developed for one of the simplest yet …

Thermalization by off-shell processes: The virtues of small virtuality
D Boyanovsky - Physical Review D, 2022 - APS
We study the thermalization of a scalar field Φ coupled to two other scalar fields χ 1, 2 that
constitute a bath in thermal equilibrium. For a range of masses the Φ propagator features …

Threshold and infrared singularities: Time evolution, asymptotic state, and entanglement entropy
D Boyanovsky - Physical Review D, 2022 - APS
Threshold and infrared divergences are studied as possible mechanisms of particle
production and are compared to the usual decay process in a model quantum field theory …

The Study of the Standard Model Electroweak Precision Physics at Future Electron-Positron Colliders
L Chen - 2022 - search.proquest.com
Future electron-positron colliders, such as the CEPC, FCC-ee, and ILC, usher in a new
precision frontier where the electroweak (EW) sector of the Standard Model (SM) of particle …
