abstract

We study the trispectrum of the gravitational waves (GWs) generated through the dynamics of an axionic spectator field and SU(2) gauge fields during inflation. In non-Abelian gauge theory, the gauge fields have four-point self-interactions, which induce the tree-level GW trispectrum. We formulate this type of the GW trispectrum including the non-dynamical contributions and evaluate it in the equilateral limit as a unique signal of this model. We find that the ratio of the GW trispectrum to the cube of the scalar power spectrum can be as large as $\mathcal{O}(10^6)$ in the viable parameter space, which could be captured in the CMB observations.

  1. Kinetic Gauge Friction in Natural Inflation

    astro-ph.CO 2024-11 conditional novelty 7.0 of 10

    Kinetic gauge friction can sustain natural inflation with sub-Planckian f, and a Chern-Simons term stabilizes the perturbations, yielding CMB-compatible spectra.
