Abstract
We propose a new leptogenesis scenario in a gauged model with supersymmetry at the TeV energy scale. Instead of relying on the very small Yukawa couplings of the singlet neutrinos to generate the observed baryon asymmetry of the Universe, which requires a very large resonance enhancement, their gauge interactions are invoked. Successful leptogenesis is then possible if a particular scalar bilinear term is disallowed.
