Abstract

In the first part of the talk will be reviewed the difficulties one 
encounters when trying to induce neutrino masses and baryogenesis via 
leptogenesis at a directly testable scale (~TeV). Two models which avoid 
these difficulties will be proposed, a minimal one we call "right-handed 
sector leptogenesis" and another one based on the seesaw extended MSSM. In 
the second part of the talk, possible connections between low energy 
induced neutrino masses and dark matter will be briefly discussed, in the 
context of 1) a inert Higgs model and 2) a low energy effective model 
where a same process determines both the neutrino masses and the dark 
matter relic density.
