Tree-Level Leptogenesis Induced by Soft SUSY Breaking in NMSSM Extended by a Right Handed Neutrino Superfield

We analyse soft leptogenesis in NMSSM extended by one right-handed neutrino superfield. Our framework predicts non-zero $$\varepsilon $$ from the right-handed sneutrino decay without the presence of thermal effects that are necessary for MSSM extended by an RH superfield. We provide the required order of magnitudes of the relevant soft supersymmetry parameters to yield sufficient baryon asymmetry of the universe.
