Higgs inflation and suppression of axion isocurvature perturbation
arXiv:1505.02119 · doi:10.1016/j.physletb.2015.07.001
Abstract
We point out that cosmological constraint from the axion isocurvature perturbation is relaxed if the Higgs field obtains a large field value during inflation in the DFSZ axion model. This scenario is consistent with the Higgs inflation model, in which two Higgs doublets have non-minimal couplings and play a role of inflaton.
