  Within the extension of MSSM by two right handed neutrinos, which masses are
degenerate at tree level, we address the issue of leptogenesis. Investigating
the quantum corrections in details, we show that the lepton asymmetry is
induced at 1-loop level and decisive role is played by the tau lepton Yukawa
coupling. On a concrete and predictive neutrino model, which enables to predict
the CP violating $\delta $ phase and relate it to the cosmological CP
asymmetry, we demonstrate that the needed amount of the baryon asymmetry is
generated via the resonant leptogenesis.
