Cosmological gravitational particle production and its implications for cosmological relics

EW Kolb, AJ Long - Reviews of Modern Physics, 2024 - APS
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 …
