Space-time curvature coupling of spinors in early universe: Neutrino asymmetry and a possible source of baryogenesis

Ujjal Debnath, Banibrata Mukhopadhyay, Naresh Dadhich

It is well known that when a fermion propagates in curved space-time, its spin couples to the curvature of background space-time. We propose that this interaction for neutrinos pro…
