Unified Origin of Curvature Perturbation and Baryon Asymmetry of the Universe
Anish Ghoshal, Abhishek Naskar, Nobuchika Okada
We propose a unified framework that describes both the curvaton mechanism for generating primordial density fluctuations and the Affleck-Dine (AD) mechanism for baryogenesis. By in…

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.…
