  • A bstractWe demonstrate that Chromo-Natural Inflation can be made consistent with observational data if the SU(2) gauge symmetry is spontaneously broken. Working in the Stueckelberg limit, we show that isocurvature is negligible, and the resulting adiabatic fluctuations can match current observational constraints. Observable levels of chirally-polarized gravitational radiation (r ∼ 10−3) can be produced while the evolution of all background fields is sub-Planckian. The gravitational wave… CONTINUE READING
