Triplet Scalar Dark Matter and Leptogenesis in an Inverse See-Saw Model of Neutrino Mass Generation

Understand

We propose a UV completion of the inverse see-saw scenario using fermion SU(2) triplet representations.

• Within this framework, a variation of the standard thermal leptogenesis is achievable at the O(TeV) scale, owing to the presence of a viable dark matter candidate.
• This baryogenesis scenario is ruled out if a triplet fermion is observed at the LHC.
• The dark matter is given by the lightest neutral component of a complex scalar SU(2) triplet, with mass in the TeV range.
