[en] A comparison of neutral and charged current deep inelastic neutrino interactions is made in an experiment utilizing the Fermilab 15 ft. bubble chamber. The ratio of neutral current events (NC) to charged current events (CC) is 0.35 +- 0.06 when the visible hadronic energy is greater than 10 GeV. The distributions of NC and CC in a new variable called u/sub vis/, which depends only on the observed hadrons, are given. From these distributions and the assumption that the x distribution is the same for NC and CC, it is concluded that for a NC y distribution of the form (1 - eta) + 3 eta(1 - y)², eta = .12 +- .32. The ratio rho/sub NC/(rho/sub CC/) of neutron to proton cross sections in NC(CC) is studied and the quotient rho/sub NC//rho/sub CC/ = 0.7 +- 0.2. The distribution of hadrons in z/sub vis/, the scaled hadronic momentum, is given. The CC hadrons fit the predictions of the quark fragmentation functions D/sub u//sup π⁺/(z) and D/sub u//sup π^-/(z) as given by Field and Feynman. The neutral current events fit the form (1 - lambda)D/sub u//sup π⁺/(z) + lambda D/sub d//sup π⁺/(z) for positives and (1 - lambda)D/sub u//sup π^-/(z) + lambda D/sub d//sup π^-/(z) for negatives with lambda = 0.56 +- 0.10 and a fit confidence level of 4%

[en] The plans for increases in the Tevatron proton-antiproton collider luminosity in the near future (Run II) and the more distant future (TeV33) are described. While there are many important issues, the fundamental requirement is to produce more antiprotons and to use them more efficiently

[en] The experiment was designed to measure the fluxes and polarizations of the hyperons by measuring the spin precession of a polarized hyperon beam

[en] The design of the Fermilab antipp collider is described. The design calls for a luminosity of 10³⁰ cm^-2 sec^-1 at a collision energy of approximately 2 TeV in the center of mass. Enough antip's to fill the collider are collected every 2 hours

[en] Preliminary results from Fermilab experiment E-497 on the magnetic moments of the Σμ and Σ^- are given. The experiment was designed to measure the fluxes and polarizations of the hyperons. It is possible to measure the magnetic moment by measuring the spin precession of a polarized hyperon beam. 6 references

[en] The Fermilab Antiproton Source has been in operation since October 1985 and has been used to provide the antiprotons used in a five month long run of the Tevatron in the Collider mode. This paper reviews the performance of the Source during the period. The Source accumulated antiprotons at a rate of approximately 10% of the design value; the causes for this lower performance are discussed. Improvements in the stochastic cooling, the RF systems, and the acceptance of the Accumulator are described

[en] The inclusive distributions of hadrons produced in γsub(μ)(anti γsub(μ))Ne interactions are found to be similar to inclusive distributions in π^+-Ne interactions. (Auth.)

[en] We have examined the inclusive production of nonstrange particle resonances in νp interactions using the Fermilab 15-ft bubble chamber. A sample of 2437 charged-current events with visible longitudinal momentum greater than 10 GeV/c was obtained. The rho⁰ and Δ⁺⁺(1232) are seen. An overall rate of 0.21 +- 0.04 rho⁰ per event is found. For five-prong events, the rate is 0.44 +- 0.08 rho⁰ per event. The rho⁰ Z distribution falls rapidly for Z greater than 0.4. The production of Δ⁺⁺ is seen clearly in events with an identified proton. No evidence is seen for Δ⁰ production. An upper limit of 0.34 is placed on the ratio of eta/π⁰

[en] We present results for the reactions vp → μ^-π⁺p and vp → μ^-K⁺p at energies above 5 GeV. The average cross section for the first reaction between 15 ad 40 GeV is (0.80 +- 0.12) x 10^-38 cm² and for events with M/sub π/+p-italic < 1.4 GeV is (0.55 +- 0.08) x 10^-33 cm². The ratio of the cross section for the second reaction to that for the first is 0.017 +- 0.010

[en] The ratio of neutral-current to charged-current cross sections is determined from a sample of events obtained in an exposure of the Fermilab 15-ft hydrogen bubble chamber to a high-energy, horn-focused neutrino beam. For evens with three or more prongs and with visible hadron momentum above 10 GeV/c, the ratio is 0.40 +- 0.14. A Monte Carlo calculation assuming the Weinberg-Salam model is used to correct for excluded events, yielding R/sub NC/CC/ = 0.48 +- 0.17
