- Dirac Leptogenesis in Extended nMSSM

- Abstract: We show that a version of the nearly Minimal Supersymmetric Standard Model (nMSSM), extended only in the singlet sector to include the additional superfields of right-handed neutrinos and very heavy Dirac particles conserving B-L, admits a viable scenario for Dirac leptogenesis and naturally small Dirac neutrino masses. The origin of the (B-L)-conserving high singlet neutrino scale and the desired supersymmetry breaking terms is associated with dynamical supersymmetry breaking in the hidden sector.
