Particle production in modified gravity in the early and present day universe

Research output: Contribution to journalArticlepeer-review

Abstract

Gravitational equations of motion in modified theories of gravity have oscillating solutions, both in the early and in the present day universe. Particle production by such oscillations is analyzed and possible observational consequences are considered. This phenomenon has impact on energy spectrum of cosmic rays and abundance of dark matter particles.
