Radiative inflation and dark energy RIDEs again after BICEP2
Following the ground-breaking measurement of the tensor-to-scalar ratio r=0.20+0.07-0.05 by the BICEP2 collaboration, we perform a statistical analysis of a model that combines Radiative Inflation with Dark Energy (RIDE) based on the M2|Φ|2 ln (|Φ|2/Λ2) potential and compare its predictions to those based on the traditional chaotic inflation M2|Φ|2 potential. We find a best-fit value in the RIDE model of r=0.18 as compared to r=0.17 in the chaotic model, with the spectral index being nS=0.96 in both models.
