New ways to TeV scale leptogenesis

Abstract

We show that by adding to the standard model plus the type I seesaw different types of scalars, it is possible to construct models that satisfy the three requirements of (i) generating neutrino masses at the TeV scale, (ii) being testable at the LHC via direct production of new states, and (iii) allowing for leptogenesis at temperatures $T\sim O$(TeV).
