Jarlskog invariant of the neutrino mapping matrix Original Research Article

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