Supercollider signatures and correlations of heavy neutrinos

Forthcoming proton supercolliders can discover a heavy neutrino lying hidden in the ${10}^2$-${10}^3$ GeV mass range, one that may harbinger a new set of heavy particles. For an unstable neutrino, the optimal search strategy will be to study a final state of charged dileptons and jets without missing $p_T$. Dilepton charge signs or angular correlations can discriminate between Dirac and Majorana heavy neutrinos.
