ABSTRACT: We revisit the current experimental bounds on fourth-generation Majorana neutrino masses, including the effects of right handed neutrinos. Current bounds from LEP‑II are significantly altered by a global analysis. We show that the current bounds on fourth generation neutrinos decaying to e W and μ W can be reduced to about 80 GeV (from the current bound of 90 GeV), while a neutrino decaying to τ W can be as light as 62.1 GeV. The weakened bound opens up a neutrino decay channel for intermediate mass Higgs, and interesting multi-particle final states for Higgs and fourth generation lepton decays.
