Structure functions obtained from high energy neutrino and antineutrino scattering from an iron target are presented. These were extracted from the combined data of Fermilab experiments E616 and E701; these utilized narrow band beam runs between 1979–1982. The structure functions are used to test the validity of quarkparton model (QPM) predictions and to extract the QCD scale parameter Λ from fits to the Altarelli-Parisi equations. 相似文献

We report a measurement of the electroweak parameters sin2θ w and ? based on the ratios of neutral current to charged current events measured in the Fermilab narrow-band neutrino beam at energies of 30–240 GeV. The data are fully corrected for radiative effects, heavy-quark production, and other effects. The best value for sin2θ w obtained, sin2θ w =0.239±0.011, is consistent with the most recent values fromW andZ production, as well as from other neutrino experiments. 相似文献

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 present measurements of the cross section for inclusive D and K meson production in e+e? annihilation in the center of mass energy range 3.6 to 5.8 GeV. D production accounts for most of the increase in the total cross section for hadron production in e+e? annihilation at energies above 4 GeV. 相似文献

Inclusive momentum and energy spectra of neutral and charged D-mesons produced in e+e? annihilation at energies near 7 GeV are presented. The slope of the energy spectrum is similar to the charged pion spectrum at the same energy. The inclusive cross section σ(e+e?→ D or + anything) at 7 GeV is 4.8±1.3 nb. 相似文献

We have observed Cerenkov light, well below threshold, in an integrating Cerenkov counter used to determine particle composition of the secondary hadron beam, which is the source of Fermilab narrow-band neutrinos. The phenomenon can be understood in terms of diffraction effects in a finite length counter caused by radiation emitted by particles traversing the counter even when it is evacuated. At zero pressure, the light can be considered as transition radiation produced when particles enter and leave the counter. A standard Cerenkov diffraction formula describes both the normal Cerenkov radiation and the light emitted below Cerenkov threshold. 相似文献
