which indicates electron-flavor effect plays a crucial role in reproducing BAU. If we take, for example, δ$_{N}$$_{3}$$_{η}$ = 10 − 5 the magnitude of washout factors are given as

and Fig. 8 shows the behavior of η$_{B}$ as functions of θ$_{13}$ and θ$_{23}$ , representing a successful leptogenesis in the range of 1 σ neutrino oscillation data. 

In weak wash-out regime K e 3 ≪ K µτ 3 < 1, assumed that N$_{3}$ is not initially present in the plasma, but they are generated by the inverse decays and scatterings, the resulting baryon-to-photon ratio η$_{B}$ including lepton flavor effects can be simply given as

where in this approximation ε µ 3 + ε τ 3 = − ε e 3 is used, and K$_{3}$ = K e 3 + K µ 3 + K τ $_{3}$. This case indicates muon- and tau-flavor effects play a crucial role in reproducing BAU. For example, for δ$_{N}$$_{3}$$_{η}$ = 10 − 6 the magnitude of washout factors are given as

In the case of M$_{2}$ ⪆ ¯ m$_{η}$ , for M$_{1}$ > M$_{3}$ > M$_{2}$ ≳ ¯ m$_{η}$ which corresponds to degenerate normal mass ordering of light neutrinos, from Eq. (13) and Eq. (39), the wash-out parameters
