Gravitational production of heavy particles during and after inflation

Abstract We investigate the gravitational production of a scalar field χ with a mass exceeding the Hubble scale during inflation m χ ≳ H I , employing both analytical and numerical approaches. We demonstrate that the steepest descent method effectively captures the epochs and yields of gravitational...
