It is found that at the first stage of reheating the classical inflation field rapidly decays into particles or into other bosons due to a broad parametric resonance, which implies that the inflation field can be a dark matter candidate.
Abstract
The theory of reheating of the Universe after inflation is developed. We have found that typically at the first stage of reheating the classical inflation field $\ensuremath{\varphi}$ rapidly decays into $\ensuremath{\varphi}$ particles or into other bosons due to a broad parametric resonance. Then these bosons decay into other particles, which eventually become thermalized. Complete reheating is possible only in those theories where a single particle $\ensuremath{\varphi}$ can decay into other particles. This imposes strong constraints on the structure of inflationary models, and implies that the inflation field can be a dark matter candidate.

Planck 2015 results. XX. Constraints on inflation

TL;DR: In this article, the authors report on the implications for cosmic inflation of the 2018 Release of the Planck CMB anisotropy measurements, which are fully consistent with the two previous Planck cosmological releases, but have smaller uncertainties thanks to improvements in the characterization of polarization at low and high multipoles.

Particle Physics and Inflationary Cosmology

Andrei Linde
TL;DR: A monograph on inflationary cosmology and cosmological phase transitions is presented in this article, which investigates modern cosmology's relationship to elementary particle physics and includes a non-technical discussion of the theory for those unfamiliar with the theory.
