MEASUREMENT OF THE BJORKEN X AND Y DISTRIBUTIONS IN NEUTRAL AND CHARGED CURRENT muon-neutrino INTERACTIONS

Baltay, C. ; Bregman, M. ; Caroumbalis, D. ; et al.
Phys.Rev.Lett. 52 (1984) 1948-1951, 1984.
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.

Properties of Multiplicity Distributions in $\nu A$ and $\bar{\nu}A$ Interactions at $E_{\nu/\bar{\nu}}\le 30$-{GeV}

Baranov, D.S. ; Chabrov, N.A. ; Filippov, V.A. ; et al.
Z.Phys.C 21 (1984) 189, 1984.
Inspire Record 197246 DOI 10.17182/hepdata.16364

We present data on the multiplicity structure of inclusive charged hadron production in charged current neutrino and antineutrino freon interactions in the energy range 3–30 GeV resulting from an experiment with the bubble chamber SKAT. Average multiplicities, dispersions and correlation coefficients are investigated. Furthermore, KNO-scaling is studied and average net charges are calculated in different kinematical regions. Our data are compared with results from\(\begin{array}{*{20}c}{( - )}\\v\\ \end{array} \)-interactions on an isoscalar target of “free” nucleons to study the influence of nuclear effects.

Experimental Study of Neutral Current and Charged Current Neutrino Cross-Sections

The CHARM collaboration Jonker, M. ; Panman, J. ; Udo, F. ; et al.
Phys.Lett.B 99 (1981) 265, 1981.
Inspire Record 156267 DOI 10.17182/hepdata.27136

Samples of 9200 muon-neutrino and 3800 muon-antineutrino interactions on nuclei were obtained with the fine-grain calorimeter of the CHARM Collaboration at the CERN 200 GeV narrow-band neutrino beam. The interactions were classified as either neutral-current or charged-current processes on an event-by-event basis. Neutral-current and charged-current cross sections in neutrino and antineutrino interactions are presented. From these results we deduce a statistically significant contribution of right-handed coupling to the neutral hadronic current, and a value of the electroweak mixing angle corresponding to sin 2 θ = 0.220 ± 0.014.

NEUTRAL CURRENT COUPLING IN HIGH-ENERGY NEUTRINO INTERACTIONS.

Merritt, F.S. ; Barish, B.C. ; Bartlett, J.F. ; et al.
Phys.Rev.D 17 (1978) 2199-2205, 1978.
Inspire Record 132560 DOI 10.17182/hepdata.24431

We present measured hadron energy distributions for the reactions ν(ν¯)+N→ν(ν¯)+hadrons at high energy, as well as for the similar charged-current interactions. Insofar as possible, the determination of these distributions avoids any a priori assumptions about either the neutral-current or the charged-current interactions. We further analyze the neutral-current distributions within the framework of specific models, particularly the scaling model, to obtain a positive-helicity component P=0.36±0.10, which lies between pure V−A and pure V or A, and a coupling strength of g0=0.31±0.03 relative to the charged-current interaction. These coupling parameters agree well with the predictions of the Weinberg-Salam model with sin2θW=0.33±0.07.

Experimental Limits on Heavy Lepton Production by Neutrinos

Cnops, A.M. ; Connolly, P.L. ; Kahn, S.A. ; et al.
Phys.Rev.Lett. 40 (1978) 144-146, 1978.
Inspire Record 121918 DOI 10.17182/hepdata.37905

We present upper limits on the production of heavy leptons (L±) by neutrinos via the process νμ+Ne→L±+⋯, L±→e±+ν+ν¯. These limits imply that the L− and L+, if they couple in full strength to νμ, are heavier than 7.5 and 9 GeV, respectively. They also imply that the coupling strength νμ to the recently discovered 1.9-GeV heavy lepton τ is less than 0.025 of the normal νμ−μ coupling.

Measurement of the neutral to charged current cross section ratio in neutrino and antineutrino interactions.

Holder, M. ; Knobloch, J. ; May, J. ; et al.
Phys.Lett.B 71 (1977) 222, 1977.
Inspire Record 120776 DOI 10.17182/hepdata.27510

We report on the analysis of inclusive neutral current events produced in neutrino and antineutrino narrow band beams. We find for incident neutrino energies in the range 12–200 GeV and for hadron energies above 12 GeV a neutral to charged current cross-section ratio of R v = 0.293 ± 0.010 for incident neutrinos, and R v = 0.35 ± 0.03 for antineutrinos. These ratios are consistent with the Weinberg-Salam model, with sin 2 θ w = 0.24 ± 0.02.

Dependence of nu nucleus cross-sections on the mass number

Borer, K. ; Hahn, B. ; Hofer, H. ; et al.
Phys.Lett.B 30 (1969) 572-575, 1969.
Inspire Record 63243 DOI 10.17182/hepdata.50061

High energy v -nucleus cross sections have been compared for Pb, Fe, Al and C as target nuclei, exposed to the CERN v -beam. The events with θ vμ < 29 0 and p μ ⪆ 1 GeV /c have rates in the ratio of the mass number of the nuclei. Also a restricted sample with q 2 ⪅ 0.1 (GeV/ c ) 2 and θ vμ < 5 0 does not reveal a theoretically predicted deviation from A -proportionality, although due to the limited statistical accuracy in this restricted sample an “ A 2 3 - contribution ” of several tenths cannot be excluded either.
