Abstract

The quasi-degeneracy of heavier sterile neutrino masses in the Neutrino Minimal Standard Model (νMSM) facilitates the production of lepton asymmetry below the electroweak scale. The first order loop corrections to this mass-difference has been computed in this work along with a numerical estimate of the contribution.
