Resumen

The possibility of low scale leptogenesis in the minimal supersymmetric standard model extended with right handed neutrinos was investigated. new sources of leptons number violation were introduced by soft symmetry breaking for the interactions. A hierarchy between the couplings of virtual and and real particles entering in the leptogenesis diagrams was involved. It was observed that the interactions were less constrained by neutrino masses and allowed larger asymmetries at low scale.
