Primordial non-Gaussianity as a probe of seesaw and leptogenesis
Chee Sheng Fong, Anish Ghoshal, Abhishek Naskar +2
We present the possibility that the seesaw mechanism and nonthermal leptogenesis can be {investigated} via primordial non-Gaussianities in the context of a majoron curvaton model.…

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…
