Abstract

Data taken with the OPAL detector at LEP during a scan of the Z⁰ resonance were searched for evidence of neutral heavy leptons that decay via mixing. Four different decay modes of the neutral heavy lepton are considered: L⁰→eW^*, L⁰→μW^*, L⁰→τW^*, and L⁰→vZ^*. No evidence is seen of a neutral heavy lepton signal; branching fraction limits in the range of 10^-3-10^-4 are set for Z⁰→L⁰L⁰ and for Z⁰→vL⁰ (orvL⁰) relative to Z⁰→hadrons.

N2 - Data taken with the OPAL detector at LEP during a scan of the Z0 resonance were searched for evidence of neutral heavy leptons that decay via mixing. Four different decay modes of the neutral heavy lepton are considered: L0→eW*, L0→μW*, L0→τW*, and L0→vZ*. No evidence is seen of a neutral heavy lepton signal; branching fraction limits in the range of 10-3-10-4 are set for Z0→L0L0 and for Z0→vL0 (orvL0) relative to Z0→hadrons.
