Generalising Axion-like particle as the curvaton: sourcing primordial density perturbation and non-Gaussianities

Anish Ghoshal, Abhishek Naskar

We investigate the non-perturbatively generated axion-like particle (ALP) potential, involving fermions in the dark sector that couple to the ALP, in an early cosmological inflatio…
