Pseudoscalar inflation or axion inflation is one of the most well-motivated models of inflation because the approximate shift symmetry guarantees the flatness of the potential against the quantum corrections. The CP and shift symmetric properties of pseudoscalar inflaton allows it to have a coupling to the Chern-Pontryagin density of the gauge fields. In this talk, I will argue that if the inflaton has such a coupling to the hyper U(1) gauge fields in the Standard Model, it can give a …
