Rate of Dimuon Production from Neutrinos and Antineutrinos at High Energy

Abstract

We present data on dimuon-production rates from neutrinos and antineutrinos in the energy range 45-205 GeV. The measurements were made using the Fermilab narrow-band beam. At higher energies (\ensuremath{\gtrsim}100 GeV), the dimuon-production rates relative to single-muon production for events within our kinematic cuts are about 1%. The numbers are consistent with calculations of Glashow-Iliopoulos-Maiani (four-quark) models and do not require the introduction of additional quarks.
