摘要: Abstract We report on the first observation of neutrino induced production muon pairs in electromagnetic field a nucleus. The data has been obtained using CHARM II detector exposed to CERN wideband and antineutrino beams. A clear signal 55 ± 16 events is seen sample dimuons opposite charge without visible recoil at vertex. cross section determined found be agreement with standard model prediction.
