Content
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.)
