Reheating Temperature from D-Term Cosmological Inflation Braneworld

The D-term inflation in supergravity, in the braneworld Randall Sundrum II (RSII) context, has been proposed to solve some problems related to the four-dimensional inflation model. That scenario is based on a modification of the Friedmann equation by the addition of the fifth dimension, which corresponds to an energy, called brane tension λ. Therefore, we propose the investigation of the brane effect on the reheating epoch. In this context, we have analyzed the process of reheating and focused on the variation of the temperature value Tre. We found that it depends on all parameters, and the value found is in the range Tre ∼ (7.5 × 108−8 × 1010) GeV, which is consistent with the thermal leptogenesis (Tre ≥ 108 GeV).
