SUMMARY:Dirac Leptogenesis in Extended nMSSM\, NPAC (Nuclear/Particle/
 Astro/Cosmo) Forum\, Eung Jin Chun\, KIAS
DESCRIPTION:We show that a version of the nearly Minimal Supersymmetri
 c Standard Model (nMSSM)\, extended only in the singlet sector to incl
 ude the additional superfields of right-handed neutrinos and very heav
 y 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 super
 symmetry breaking terms is associated with dynamical supersymmetry bre
 aking in the hidden sector.
