Abstract
We study the possibility of realising successful leptogenesis from dark matter annihilations in the
scotogenic model of neutrino masses to explain the same order of magnitude abundance of dark
matter and baryons in the present Universe, and show that the correct leptonic asymmetry, dark
matter abundance and neutrino mass can be simultaneously achieved in the model. Interestingly,
the scale of leptogenesis can be as low as 5 TeV, lower than the one in vanilla leptogenesis scenario
in scotogenic model along with the additional advantage of explaining the baryon-dark matter
coincidence. Due to such low scale, the model remains predictive at dark matter direct detection
and rare decay experiments looking for charged lepton flavour violating processes
