Tree-level unitarity in Higgs inflation in the metric and the Palatini formulation
Asuka Ito, Wafaa Khater, Syksy Rasanen
We calculate the tree-level amplitudes for electrically neutral scattering for the Standard Model Higgs doublet non-minimally coupled to the Ricci scalar. We consider both…

Analytic formula for the dynamics around inflation end and implications on primordial gravitational waves
Asuka Ito, Jiro Soda, Masahide Yamaguchi
We argue that primordial gravitational waves have a spectral break and its information is quite useful for exploring the early universe. Indeed, such a spectral break can be a fing…

Dressed Power-law Inflation with Cuscuton
Asuka Ito, Aya Iyonaga, Suro Kim +1
We study dressed inflation with a cuscuton and find a novel exact power-law solution. It is well known that the conventional power-law inflation is inconsistent with the Planck dat…
