Abstract

Analysis of 122 965 dimuon final states produced by 209-GeV muons in a magnetized iron calorimeter has set a lower limit on the mass of a neutral heavy muon (M̄0). If the M̄0 is coupled with Fermi strength to a right-handed charged current and decays to μμν with a 10% branching ratio, its mass exceeds 9 GeV/c2.
