The minimal SU(5) theory augmented by the fermionic adjoint representationrestores the coupling constant unification and gives realistic neutrino massesand mixing through the hybrid Type I and Type III seesaw. The crucialprediction of the theory is an SU(2) lepton triplet with the mass below TeV. Westudy the signature of these heavy leptons and propose the strategy to testthis mechanism at the hadron and lepton colliders. The smoking gun evidence ofthe theory is Delta L=2 lepton number violation through events of a pair oflike-sign leptons plus four jets without significant missing energy at hadroncolliders. We find that via this unique channel, the heavy lepton can besearched for up to a mass of 200 GeV at the Tevatron with 8 fb^-1, and up to450 (700) GeV at the LHC of 14 TeV C.M.energy with 10 (100) fb^-1. The signalrate at the 10 TeV LHC is reduced to 60-35% for a mass of 200-700 GeV. We alsocomment on how to distinguish this theory from other models with similar heavyleptons. Finally, we compare the production rates and angular distributions ofheavy leptons in e+e- collisions for various models.
