We consider a generic model with four gauge singlets which generates successfully the right amount of baryon asymmetry through leptogenesis at the TeV scale. It also reproduces left-handed neutrino masses compatible with present data. In the present work, we perform a study of thermal production mechanisms of the lightest right-handed neutrino N1 responsible for the lepton asymmetry taking into account all dominant processes (decays, ΔL = 1 and ΔL=2 scatterings) by solving the full Boltzmann equations.
