Measurement of the Difference in R = $\sigma^-$l / $\sigma^-$t and $\sigma$(a) / $\sigma(D$) in Deep Inelastic $e D$, $e$ Fe and $e$ Au Scattering

We measured the differences in R=σLσT and the cross-section ratio σAσD in deep-inelastic electron scattering from D, Fe, and Au nuclei in the kinematic range 0.2≤x≤0.5 and 1≤Q2≤5 (Gev/c)2. Our results for RA−RD are consistent with zero for all x and Q2, indicating that possible contributions to R from nuclear higher-twist effects and spin-0 constituents in nuclei are not different from those in nucleons. The European Muon Collaboration effect is reconfirmed, and the low-x data from all recent experiments, at all Q2, are now in agreement.

Measurement of the Bjorken X and Y Distributions in Neutral and Charged Current $\nu_{\mu}$ Interactons

Baltay, C. ; Bregman, M. ; Caroumbalis, D. ; et al.

Inspire Record 205295 DOI 10.17182/hepdata.20446

Distributions of the Bjorken scaling variables x and y, and the structure function F+(x), are presented both for neutral-current and for charged-current νμ interactions. The data were obtained by use of the Fermilab 15-ft neon bubble chamber exposed to a narrow-band νμ beam. Results are based on 151 neutral-current and 683 charged-current events. An important feature of the neutral-current analysis is the event-by-event reconstruction of the outgoing neutrino.

Measurements of the a-Dependence of Deep Inelastic electron Scattering from Nuclei

Arnold, R.G. ; Bosted, Peter E. ; Chang, C.C. ; et al.
Phys.Rev.Lett. 52 (1984) 727, 1984.
Inspire Record 193846 DOI 10.17182/hepdata.20435

The deep-inelastic electron-scattering cross sections per nucleon σA for D, He, Be, C, A1, Ca, Fe, Ag, and Au were measured in the kinematic range 0.09<~x<~0.9 and 2<~Q2<~15 (GeV/c)2 with use of electrons with energies ranging from 8 to 24.5 GeV. The ratio σAσD is consistent with unity in the range 0.1<x<0.3. For 0.3<x<0.8, the ratio decreases logarithmically with atomic weight A, or linearly with average nuclear density. No Q2 dependence in the ratio was observed over the kinematic range of the data.

MEASUREMENT OF THE muon-neutrino CHARGED CURRENT CROSS-SECTION

Baker, N.J. ; Connolly, P.L. ; Kahn, S.A. ; et al.
Phys.Rev.Lett. 51 (1983) 735-738, 1983.
Inspire Record 183068 DOI 10.17182/hepdata.20488

The Fermilab 15-ft bubble chamber, filled with a heavy neon-hydrogen mix, was exposed to a narrow-band νμ beam. Based on the observation of 830 charged-current νμ interactions, the cross section was found consistent with a linear rise with the neutrino energy in the interval 10 GeV<~Eν≲240 GeV. The average slope was determined to be σνEν=(0.62±0.05)×10−38 cm2 GeV−1.

CROSS-SECTIONS AND SCALING VARIABLE DISTRIBUTIONS OF NEUTRAL AND CHARGED CURRENT NEUTRINO NUCLEON INTERACTIONS FROM A LOW-ENERGY NARROW BAND BEAM

Phys.Rev.Lett. 44 (1980) 916-919, 1980.
Inspire Record 157494 DOI 10.17182/hepdata.20725

This Letter compares neutral-current and charged-current scaling-variable distributions in neutrino-nucleon interactions induced by a narrow-band beam at Brookhaven National Laboratory; the x distribution of neutral-current events has been reported previously. The first measurement of flux-normalized neutrino cross sections from a narrow-band beam in the energy range Eν=3−9 GeV is also presented.
