Query: Exotic Seesaw-Motivated Heavy Leptons at the LHC   We study the LHC potential for discovering TeV-scale SU(2)_L 5-plet fermions
introduced recently to explain small neutrino masses. We show that the
Drell-Yan production and the decays of new exotic Sigma leptons are testable at
the LHC. Their production is abundant due to nontrivial electroweak gauge
charges. For 1 fb^-1 of integrated luminosity at the present LHC sqrt{s}=7 TeV,
there can be 270 Sigma-Sigmabar pairs produced for M_Sigma = 400 GeV. Besides
producing same-sign dilepton events, they could lead, due to a chosen small
mixing between heavy and light leptons, to ~10 golden decays
Sigma^{+++}(Sigma^{+++}-bar) --> W^\pm W^\pm l^\pm with a specific decay
signature.
