Dimuon production by high-energy neutrinos and antineutrinos in the fermilab 15-foot bubble chamber
The Fermilab fifteen foot bubble chamber/two-plane External Muon Identifier (EMI) hybrid detector filled with Ne(47% atomic)-H/sub 2/ is exposed to the quadrupole triplet beam (< E/sub nu//sub mu > = 89 GeV, = 60 GeV). In 326000 pictures there are 10148 neutrino and 1773 antineutrino charged current events with two-plane EMI muon identification and muon momenta >4 GeV/c. In this sample there are 55 ..mu..-..mu../sup +/X, 11 ..mu..-..mu..-X and 0 ..mu../sup +/..mu../sup +/X candidates with muon momenta >4 GeV/c. The like-sign events are consistent with background. The opposite-sign dimuons occur at R..mu mu.. = 0.35 +- 0.10% of the single muon rate. The nu/sub mu/-induced ..mu..-..mu../sup +/ rate is 0.20 +- 0.15% below E/sub nu//sub mu/ = 100 GeV and 0.50 +- 0.30% above 100 GeV. In the opposite sign dimuons there are 10 candidates with an associated V/sup 0/ implying 0.76 +- 0.36 neutral strange particle per opposite sign dimuon event. The production rate, excess of neutral strange particles, and kinematic distributions of the dimuon events are consistent with the charm model predictions.
