Search for muon neutrino and antineutrino oscillations in the mass range 15<Δ m 2 <1,000 eV 2 /c 4

A search for inclusive muon-neutrino (vµ) and muon-antineutrino\((\bar v_\mu )\) oscillations has been performed in the Fermilab narrow band neutrino beam using two detectors running simultanously at two distances from the neutrino source. The data show no evidence for either neutrino or antineutrino oscillations and rule out oscillations ofvµ or\(\bar v_\mu \) into any other single type of neutrino for 15<Δm2<1,000 eV2/c4 and sin2(2θ)>0.02–0.40.
