Abstract
We study matter-antimatter asymmetry of the universe in terms of Baryogenesis through leptogenesis in standard Type-I seesaw scenario where charged lepton mass matrix is assumed to take diagonal form. Considering the CP violating out of equilibrium decay of the lightest right handed neutrino, we have studied the Baryon asymmmetry of the universe by varying Majorana CP violating phase (αβ ), Dirac CP violating phase and the lightest neutrino mass. We also constrain the free parameters in the light neutrino sector (mlightest ,δ,α,β ) to certain range of values which values can be tested in ongoing and future neutrino experiments.
