  We investigate the parameter space of the minimal inverse seesaw ISS(2,2)
model for successful leptogenesis. The framework of ISS(2, 2) is realized by
augmenting the Standard Model with two right-handed and two Standard Model
singlet neutrinos. The decay of the heavy sterile states which is essentially
an admixture of the right-handed and SM singlet neutrino states produces the
baryon asymmetry of the universe. In this predictive model of leptogenesis, we
study resonant leptogenesis where the mass splitting between the heavy sterile
states is naturally achieved. We review the possibility of generating the
observed baryon asymmetry of the universe via leptogenesis where the CP
violation comes solely from the low-energy CP phases. In addition, we study the
effect of texture zero in the Dirac mass matrix on the parameter space of the
model for successful resonant leptogenesis.
