Study of wrong sign muon and trimuon events in neutrino-nucleon scattering

Book ·
OSTI ID:6845425
Wrong sign muon events in neutrino-nucleon scattering are characterized by a single muon in the final state carrying lepton number different from that of the incident neutrino. A search for such events in two experiments employing the Fermilab Narrow Band Neutrino beam is reported here. The author derives an upper limit of 3.1 x 10/sup -4/ on the rate of production of these events. Limits on the intrinsic charm content of the sea (<.02), flavor changing neutral current (<.0085), and lepton number violating processes (rate < 7.1 x 10/sup -5/) have also been derived. Further, if the lepton number violation is brought about by a massless Majorana neutrino with a non-zero right handed coupling, then these data set the upper limits on the mass of the right handed gauge boson (>849 GeV) and its mixing angle with the ordinary boson (<009). The rate and kinematical properties of wrong sign events are compared with those of the neutrino induced dimuon events. Finally the author reported on a set of 12 neutrino initiated trimuons, with muon momentum > 4.5 GeV. The author concluded that the trimuon events could be understood in terms of the hadronic and the radiative production of an extra dimuon pair in a charged current event.
