Cosmological gravitational particle production and its implications for cosmological relics
Edward W. Kolb, Andrew J. Long
Abstract
Expansion of the Universe creates the conditions for particle production solely due to the presence of gravity. This review provides a field-theoretical description of particle creation in a time-dependent background and explores the consequences of cosmological gravitational particle production for dark matter, gravitational-wave radiation, dark radiation, and the baryon asymmetry of the Universe.
