Large tensor-to-scalar ratio from supersymmetric hybrid inflation potential

Presented by Osamu SETO on 22 Jul 2014 from 17:50 to 18:10
Type: Particle Cosmology
Track: Particle Cosmology


We show in double inflation scenario where a second inflation follows hybrid inflation, the supersymmetric hybrid inflation with a coupling of the order of unity can generate a large tensor perturbatio. This scenario would relax the tension between BICEP2 and Planck concerning the tensor-to-scalar ratio, because a negative large running can also be obtained for a certain number of e-fold of the hybrid inflation. (This is based on arXiv:1404.3102.)
