Radiative decay as the signal of a heavy neutrino at the SSC

The one-loop decay N→νγ is studied for a heavy neutrino N whose mass cannot be neglected during the loop calculation. The event rates for the resulting signal at the SSC are found to be experimentally accessible if mN<MW, so that N has only three-body decays at the tree level. The usefulness of such decays in identifying a heavy neutrino is also discussed
