Abstract
A vector-like charged singlet lepton in the mass range m H+ m τ < m L< m W is a good source of the standard model Higgs boson, via its decay mode L→ τH. In the e +e − collisions at LEP II, Higgs boson production from this source is about an order of magnitude larger than that from the standard Bjorken process. This is also a very clean signal for the singlet lepton, as the associated backgrounds are several orders of magnitude smaller. We also discuss how the singlet signals can be distinguished from those of a sequential doublet lepton.
