Neutrino-Antineutrino Asymmetry From The Space-time Noncommutativity

High Energy Physics - Theory 2021-02-25 v1

Abstract

A new mechanism having as an origin the space-time noncommutativity has been shown to generate anisotropy and axial-like interaction giving rise to a leptonic asymmetry for fermionic particles propagating in a curved noncommutative FRWFRW universe. As a by-product, for ultra-relativistic particles like neutrinos, an analytical expression of this asymmetry is derived explicitly. Constraints and bounds from the cosmological parameters are also discussed.
