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.

AbstractThis paper reports on measurements of the total cross section for the inclusive reaction vμ+N, as a function of incident energy. Neutrinos and antineutrinos with energy in the range 30–300 GeV were produced in the 1982 Fermilab narrow-band neutrino beamline. A total of 35 000 neutrino and 7000 antineutrino interactions were recorded in the CCFR detector located in LabE. The incident neutrino flux was determined by methods similar to those used in previous experiments. The rate of increase with energy of the total cross section (σ/Ev) in the range 30 to 75 GeV was determined to be 0.659±0.005(stat)±0.039(syst)×10−38 cm2/GeV and 0.307±0.008(stat)±0.020(syst)×10−38 cm2/GeV for incident neutrinos and antineutrinos, respectively. The 5.9% systematic errors are due primarily to uncertainties in the flux intensity measurement. The energy dependence of the cross section in the regionEν=100–300 GeV was found to be linear, as determined by relative normalization techniques. A weighted average of our previous and present measurement for the total ν-N cross section yields:

Abstract We describe a high statistics measurement from deep inelastic neutrino-nucleon scattering of the electroweak parameters ϱ and sin 2 θ w , performed in the Fermilab narrow-band neutrino beam. Our measurement uses a radius-dependent cut in y = E H / E v which reduces the systematic error in sin 2 θ w , and incorporates electromagnetic and electroweak radiative corrections. In a renormalization scheme where sin 2 θ w ≡ 1− m 2 W / m 2 Z , a value of sin 2 θ w = 0.242±0.011±0.005 is obtained fixing ϱ = 1. If both sin 2 θ w and ϱ are allowed to vary in a fit to our data, we measure ϱ = 0.991 ± 0.025 ± 0.009.

Abstract We present data on the punchthrough probability for showers of positively charged hadrons with momenta 15, 25, 50, 100, 200, and 300 GeV/c. Data were taken using the CCFR neutrino detector (the Lab E detector), an iron calorimeter instrumented with counters every 10 cm of iron, and drift chambers every 20 cm of iron.
