Description
A search for νμ → νe and anti νμ → anti νe oscillations has been carried out with the CHARM II detector exposed to the CERN wide band neutrino beam. The data were collected over five years, alternating beams mainly composed of muon-neutrinos and muon-antineutrinos. The number of interactions of νe and anti νe observed is comparable with the number of events expected from flux calculations. For large squared mass differences the upper limits obtained on the mixing angle are sin22θ < 9.4 . 10-3 for νμ oscillating to νe and sin22θ < 4.8 . 10-3 for anti νμ to anti νe, at the 90% confidence level. Combining neutrino and antineutrino data the upper limit is 5.6 . 10-3. (orig.)
