AbstractAbstract
[en] The discussion of high energy (10 to 200 GeV) antineutrino interactions with nucleons in the hydrogen-neon filled 15-ft bubble chamber is continued. The earlier paper at this meeting presented by V. Kolganov discussed the limit in this experiment for the reaction anti nu + N yields mu+e-X. The Bjorken scaling variable distributions y and x are presented. The y distributions are fitted with a parameter B which in the quark-parton model is related to the relative antiquark content in the nucleons. The antiquark content is determined to be (10 +- 3) percent and shows no antineutrino energy dependence. A comparison is made of fitted B values for this experiment and other antineutrino experiments discussed at this meeting. The x distributions for x greater than 0.2 are consistent in shape with the structure functions extracted from e-d scattering data

AbstractAbstract
[en] Preliminary results are presented on searches for new particles produced in the interaction of antineutrinos with nucleons at 300 GeV in the 15-ft bubble chamber. Indirect tests for new particle production are made by investigating the x and y distributions of all charged current events and by investigating the general properties of events with neutral strange particles. Direct tests of new particle production are made by searching for dilepton events and by looking for peaks in the invariant mass distributions of events involving neutral strange particles. Also energy, Q2, x, and y distributions and B values are given

AbstractAbstract
[en] This paper continues the discussion of high energy (10-200 GeV) antineutrino interactions with nucleons in the hydrogen-neon filled 15-ft bubble chamber. The earlier paper at this meeting presented by V. Kolganov discussed the limit in this experiment for the reaction anti ν + N → μ+e-X. Herein we present the Bjorken scaling variable distributions y and x. The y distributions are fitted with a parameter B which in the quark-parton model is related to the relative antiquark content in the nucleons. The antiquark content is determined to be (10 +- 3)% and shows no antineutrino energy dependence. A comparison is made of fitted B values for this experiment and other antineutrino experiments discussed at this meeting. The x distributions for x > 0.2 are consistent in shape with the structure functions extracted from e-d scattering data. (orig.)

Die Arbeit setzt die Diskussion ueber Hochenergie-Antineutrinowechselwirkungen (10-200 GeV) mit Nukleonen in der wasserstoffgefuellten 15 ft-Blasenkammer fort. Ein frueherer Beitrag von V. Kolganov auf dieser Konferenz diskutierte die Grenzen dieses Experiments fuer die Reaktion anti ν + N → μ+e-X. Die vorliegende Arbeit behandelt die Bjorken scaling Variablenverteilungen y und x. Die y-Verteilungen werden mit einem Parameter B angepasst, der im Quark-Partonenmodell mit dem relativen Antiquarkinhalt der Nukleonen im Zusammenhang steht. Der Antiquarkinhalt wird mit (10 +- 3)% bestimmt und zeigt keine Antineutrino-Energieabhaengigkeit. Die gefitteten B-Werte fuer das vorliegende Experiment und ein anderes, ebenfalls auf dieser Tagung vorgelegtes Experiment werden verglichen. Die x-Beitraege fuer > 0,2 sind formkonsistent mit den aus e-d Streudaten abgeleiteten Strukturfunktionen. (orig.)Primary Subject

AbstractAbstract
[en] To increase the flux of neutrinos at the Fermilab accelerator over the entire neutrino energy spectrum, a high efficiency horn-focussed beam was developed. The horn system is well known for its high acceptance and highly achromatic focussing of charged particles formed at the production target into a low divergence beam. This meson beam is allowed to decay in a 400 m long vacuum region producing neutrinos and muons. The muons are absorbed from the beam by using 1 Km of earth, allowing the filtered neutrino beam to pass through the experimental detectors. The equipment and results of the focussing region are discussed. (auth)

AbstractAbstract
[en] The quoted flux in a recent report of a detected magnetic monopole is inconsistent by factors on the order of 500 000 with ocean-bottom searches. One resolution of this incongruity is that monopoles are trapped somewhere between the top of the atmosphere and the ocean bottom. We have searched for monopoles in the atmosphere and ocean water and have found none at levels substantially below the numbers expected if the monopoles were trapped
