Abstract
The neutral massive leptons expected in SO(10) have been studied in a model which permits neutrinos to be massless. The mixing of these leptons with ordinary neutrinos introduces violations of weak universality. Three massive leptons occur: , coupling to and with strength () relative to the ordinary weak coupling; , coupling to and with relative strength (); and , coupling to and with relative strength () and to and with relative strength (). Their masses are bounded from below by 0.37, 6, and 25 GeV, respectively. The prospects for observing the neutral massive leptons in neutrino neutral-current interactions, in and decays, and in , , and decays are discussed.
