Oscillating Chiral Tensor Spectrum from Axionic Inflation
Ippei Obata, Jiro Soda
We study the axionic inflation with a modulated potential and examine if the primordial tensor power spectrum exhibits oscillatory feature, which is testable with future space-base…

Chiral Primordial Gravitational Waves from Dilaton Induced Delayed Chromo-natural Inflation
Ippei Obata, Jiro Soda
We study inflation driven by a dilaton and an axion, both of which are coupled to a SU(2) gauge field. We find that the inflation driven by the dilaton occurs in the early stage of…
