Jarlskog invariant of the neutrino mapping matrix

Abstract: The Jarlskog Invariant of the neutrino mapping matrix is calculated based on a phenomenological model which relates the smallness of light lepton masses and (of ) with the smallness of T violation. For small T violating phase in the lepton sector, is proportional to , but and are proportional to . This leads to . Assuming , we find , consistent with the present experimental data.
