Is Higgs inflation ruled out?

Cook, Jessica L; Krauss, Lawrence; Long, Andrew J; Sabharwal, Subir


We consider the status of Higgs inflation in light of the recently announced detection of B modes in the polarization of the cosmic microwave background radiation by the BICEP2 Collaboration. In order for the primordial B-mode signal to be observable by BICEP2, the energy scale of inflation must be high: Vinf≈2×1016-GeV. Higgs inflation generally predicts a small amplitude of tensor perturbations, and therefore it is natural to ask if Higgs inflation might accommodate this new measurement. We...[Show more]
