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

Conversions and semi-annihilations of dark matter (DM) particles in addition to the standard DM annihilations are considered in a three-component DM system. We find that the relic abundance of DM can be very sensitive to these non-standard DM annihilation processes, which has been recently found for two-component DM systems. To consider a concrete model of a three-component DM system, we...
