Vectorlike leptons and long-lived bosons at the LHC
Abstract We study a renormalizable theory that includes a heavy weak-singlet vectorlike lepton, τ ′ , that decays into a pseudoscalar boson and a tau lepton. We show that this can be the dominant decay mode of τ ′ provided the pseudoscalar couplings deviate from the case of a Nambu-Goldstone boson....
