We report on a search forv μ-induced events where the single emerging muon carries lepton number opposite that of the incident neutrino. The rate and kinematic quantities of the candidate events are compared with known backgrounds from \(\bar v_\mu \) -induced charged current interactions and ν-induced interactions that produce dileptons. We derive an upper limit on the rate of wrong-sign single muon production relative to the rate ofv μ charged current interactions to be 1.6×10?4 fory<0.5 and 3.1×10?4 fory>0.5 (90% CL). These upper limits enable us to constrain exotic sources of wrong-sign muons such as the charm component of the nucleon sea, flavor changing neutral currents and lepton number violating processes. Finally, the rate and kinematic properties of these events are compared with those of the neutrino-induced opposite-sign dimuon events. 相似文献

We report the results of a study of two-color laser excitation, ω1 + ω2, in dense sodium vapor where ω1 was tuned in the vicinity of the 3P fine structure doublet and ω2 was tuned to highernl states. Resonant excitation by ω2 of higherns andnd states from one member of the 3P doublet when ω1 is tuned near the other is attributed to collisional excitation transfer. Anomalous dipole forbiddenp-p transitions are observed when ω2 is tuned to highnP states (≥20) and are believed to be DC electric field induced. Sample spectra for the processes considered are calculated and compared with experiment. 相似文献
