Description
In this paper, we investigated the influence of the CP-disrupting phase in the mixing matrix, the hierarchy of neutrino masses, and the initial lepton asymmetry in the neutrino sector on the evolution of the neutrino density matrix. The calculations were performed using the modified program code FortEPiaNO. The results obtained allow us to say with confidence that the CP phase has little effect on the evolution of the chemical potentials of active neutrinos, and the inverse neutrino hierarchy neutralizes asymmetry more efficiently and faster.
