摘要：

Following a baryogenesis scenario proposed by Lazarides, Panagiotakopoulos, and Shafi, we show how the observed baryon asymmetry can be explained via resonant leptogenesis in a class of supersymmetric models with an intermediate mass scale M(I)less than or similar to10(9) GeV. It involves the out of equilibrium decay of heavy (less than or similar toM(I)) right handed neutrinos at a temperature close to the TeV supersymmetry breaking scale. Such models can also resolve the MSSM mu problem.
