It involves the out of equilibrium decay of heavy (<~M_I) right handed neutrinos at a temperature close to the TeV supersymmetry breaking scale. Such models can also resolve the MSSM mu problem.1+9 pages, no figure, comments added, minor revisions, to appear in PRDHigh Energy Physics - Phenomenologytext
