Description

In this letter we have explored the possibility of embedding the genesis
of lepton asymmetry within the well studied Scotogenic model. We have shown that in this model one can have a Dark Matter in the TeV scale. The model is highly constrained in the context of dark matter,neutrino mass, Flavor Physics and now also gets an additional
constraint on the relative complex phases from the required lepton asymmetry which eventually converts to the observed baryonic asymmetry
through the spheleron transition during the electroweak phase transitions.
