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

The one-loop decay $N\to \nu \gamma$ 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 $m_N<M_W$, 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.
