英文摘要: It is assumed that a heavy right-handed Majorana neutrino (or more) which is a weak SU(2) singlet exists and its mixing with regular neutrinos causes a Cabibbo-Kobayashi-Maskawa-type matrix. This mixing effect may interpret some problems in tau leptonic decays. To be consistent with the requirements from both the seesaw mechanism and data on Z0 decay, the fourth generation with a heavy neutrino is needed. This also possibly provides a large destructive interference between contributions of magnetic moments of the electron neutrino and tau neutrino to explain away the puzzle about the deficiency of the solar-neutrino flux.
