Reheating in nonminimal derivative coupling model

TL;DR

This paper investigates the reheating phase in a nonminimal derivative coupling inflation model, analyzing the inflaton's oscillations, radiation production, and calculating the reheating temperature.

Contribution

It provides a detailed study of reheating dynamics and temperature in a nonminimal derivative coupling inflationary framework, which is less explored in prior research.

Findings

Reheating temperature is explicitly calculated.

Inflaton and radiation behaviors during reheating are characterized.

The model's reheating dynamics differ from minimal coupling scenarios.

Abstract

We consider a model with nonminimal derivative coupling of inflaton to gravity. The reheating process during rapid oscillation of the inflaton is studied and the reheating temperature is obtained. Behaviors of the inflaton and produced radiation in this era are discussed.
