Abstract

A search for long-lived neutral particles (N0’s) with masses above 2.2GeV/c2 that decay into at least one muon has been performed using an instrumented decay channel at the NuTeV experiment at Fermilab. Data were examined for particles decaying into the final states μμ, μe, and μ π . Three μ μ events were observed over an expected standard model background of 0.069 ± 0.010 events; no events were observed in the other modes. © 2001 American Physical Society.
