Phys. Rev. Lett. 93, 111601 (2004) [4 pages]Low-Scale Leptogenesis and Soft Supersymmetry BreakingReceived 28 April 2004; published 8 September 2004 We investigate the possibility of low-scale leptogenesis in the minimal supersymmetric standard model extended with right-handed (s)neutrinos. We demonstrate that successful leptogenesis can be easily achieved at a scale as low as ∼ TeV where lepton number and CP violation comes from soft supersymmetry breaking terms. The scenario is shown to be compatible with neutrino masses data. © 2004 The American Physical Society URL:
