It is shown that the requirement of preservation of baryon asymmetry does not rule out a scale for leptogenesis as low as 10 TeV. The conclusions are compatible with see-saw mechanism if, for example, the pivot mass scale for neutrinos is ≈ 10-2 that of the charged leptons. We explore the parameter space m̃1 - M1 of relevant light and heavy neutrino masses by solving Boltzmann equations. A viable scenario for obtaining baryogenesis in this way is presented in the context of gauged B - L symmetry. © 2005 The American Physical Society.
