Macro Reheating Properties of the Fibre Inflationary Universe

Description
In this talk, I present the first constraints on the general reheating properties of the Fibre Inflation model assuming a simple and effective reheating fluid described by an effective equation of state parameter. The results of the numerical analysis are completely independent on the details of the inflaton physics around the minimum of the potential and I illustrate the behavior of the number of e-foldings during reheating and of the reheating temperature as functions of the spectral index of the cosmological scalar perturbations. In particular, I discuss the results with respect to the current cosmological bounds, provided by the Planck missions, and with respect to the next generation of cosmological experiments.
