Query: Z' Decays into Four Fermions   If a new $Z'$ is discovered with a mass $\sim 1 \ TeV$ at LHC/SSC, its (rare)
decays into two charged leptons plus missing transverse energy will probe the
$Z'$ coupling to the lepton doublet $(\nu,e)_L$ and to $W^+W^-$, allowing
further discrimination among extended electroweak models.
