The Majorana nature of neutrinos may only be experimentally verified via lepton-number violating processes involving charged leptons. We explore the ΔL=2 like-sign dilepton production at hadron colliders to search for signals of Majorana neutrinos. We find significant sensitivity for resonant production of a Majorana neutrino in the mass range of 10–80 GeV at the current run of the Tevatron with 2  fb-1 integrated luminosity and in the range of 10–400 GeV at the CERN LHC with 100  fb-1.
