Reheating temperature in non-minimal derivative coupling model

Understand

We consider the inflaton as a scalar field described by a non-minimal derivative coupling model with a power law potential.

• We study the slow roll inflation, the rapid oscillation phase, the radiation dominated and the recombination eras respectively, and estimate e-folds numbers during these epochs.
• Using these results and recent astrophysical data we determine the reheating temperature in terms of the spectral index and the amplitude of the power spectrum of scalar perturbations.
