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 (

{\bar{M}}^{0}

). If the

{\bar{M}}^{0}

is coupled with Fermi strength to a right-handed charged current and decays to

μ μ ν

with a 10% branching ratio, its mass exceeds 9

{G e V / c}^{2}
