Gravitational Wave from Axion-SU(2) Gauge Fields: Effective Field Theory for Kinetically Driven Inflation
Yuki Watanabe, Eiichiro Komatsu
Building on Weinberg's approach to effective field theory for inflation, we construct an effective Lagrangian for a pseudo scalar (axion) inflaton field with shift symmetry. In thi…

Effects of Gravitational Chern-Simons during Axion-SU(2) Inflation
Leila Mirzagholi, Eiichiro Komatsu, Kaloian D. Lozanov +1
In this paper, we examine the viability of inflation models with a spectator axion field coupled to both gravitational and SU(2) gauge fields via Chern-Simons couplings. Requiring…
