Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating

Gravitational Particle Production of Scalars: Analytic and Numerical Approaches Including Early Reheating

Cosmological gravitational particle production (GPP) is a generic mechanism by which particles are produced during the inflationary epoch. In this work we consider the GPP of massive scalars in an effort to fully understand the spectrum of the produced particles. We consider scalars which are conformally or minimally coupled to …
