Description
- Introduce a Chern-Simons term that inflaton is coupled with a gauge boson and show that the gauge boson can be sufficiently produced during inflation.
- Constrain the mass and chemical potential of the gauge boson and the most stringent constraint is the non-Guassianity of the equilateral bispectrum.
- Show three signals of the gauge boson: oscillation with respect to the mass in the squeezed bispectrum, parity violation in the trispectrum, and gravitational waves.
