Effective treatment of U(1) gauge field and charged particles in axion inflation
Tomohiro Fujita, Jun'ya Kume, Kyohei Mukaida +1
The axionic inflaton with the Chern-Simons coupling may generate U(1) gauge fields and charged particles simultaneously. In order to incorporate the backreaction from the charged p…
On UV-completion of Palatini-Higgs inflation
Yusuke Mikura, Yuichiro Tada
We investigate the UV-completion of the Higgs inflation in the metric and the Palatini formalisms. It is known that the cutoff scales for the perturbative unitarity of these inflat…
Stochastic inflation with an extremely large number of -folds
Naoya Kitajima, Yuichiro Tada, Fuminobu Takahashi
We propose a class of single-field, slow-roll inflation models in which a typical number of -folds can be extremely large. The key point is to introduce a very shallow local min…
