TL;DR

This paper investigates inflation and reheating in a modified teleparallel gravity model, calculating the reheating temperature based on cosmological perturbations and the evolution of the universe.

Contribution

It introduces a novel teleparallel gravity framework for inflation and reheating, linking reheating temperature to observable cosmological parameters.

Findings

Reheating temperature depends on spectral index and power spectrum.

The model provides a consistent description of inflation and reheating.

Predictions align with current cosmological observations.

Abstract

We study the cosmological inflation and reheating in a teleparallel model of gravity. Reheating is assumed to be due to the decay of a scalar field to radiation during its rapid oscillation. By using cosmological perturbations during inflation, and subsequent evolutions of the Universe, we calculate the reheating temperature as a function of the spectral index and the power spectrum.
