Preheating in Dirac-Born-Infeld inflation
journal contribution
posted on 2023-06-07, 23:30 authored by Nazim Bouatta, Anne-Christine Davis, Raquel H Ribeiro, David SeeryDavid SeeryWe study how the universe reheats following an era of chaotic Dirac-Born-Infeld inflation, and compare the rate of particle production with that in models based on canonical kinetic terms. Particle production occurs through non-perturbative resonances whose structure is modified by the nonlinearities of the Dirac-Born-Infeld action. We investigate these modifications and show that the reheating process may be efficient. We estimate the initial temperature of the subsequent hot, radiation-dominated phase.
