Savior curvatons and large non-Gaussianity
Abstract Curvatons are light (compared to the Hubble scale during inflation) spectator fields during inflation that potentially contribute to adiabatic curvature perturbations post-inflation. They can alter CMB observables such as the spectral index n s , the tensor-to-scalar ratio r, and the local...
