Particle Production in Ekpyrotic Scenarios (1605.04670v1)
Published 16 May 2016 in hep-th, astro-ph.CO, gr-qc, and hep-ph
Abstract: We consider Parker particle production in the Ekpyrotic scenario (in particular in the New Ekpyrotic model) and show that the density of particles produced by the end of the phase of Ekpyrotic contraction is sufficient to lead to a hot state of matter after the bounce. Hence, no separate reheating mechanism is necessary.
