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.

Total Cross-section for Neutrino Charged Current Interactions at 3-{GeV} and 9-{GeV}

Average total cross sections are given for neutrino charged current interactions at neutrino energies of 2.87 GeV and 9.05 GeV. The ratios 〈σ〉 〈E〉 are 0.69 ± 0.05 and 0.61 ± 0.06 in units of 10 −38 cm 2 /GeV nucleon, respectively The errors include both statistical and systematic uncertainties.

Measurements of Muon-neutrino n and anti-Muon-neutrino n Charged Current Total Cross-Sections

Barish, B.C. ; Bartlett, J.F. ; Bodek, A. ; et al.
Phys.Rev.Lett. 39 (1977) 1595, 1977.
Inspire Record 5994 DOI 10.17182/hepdata.50102

Measurements of flux-normalized neutrino and antineutrino total charged-current cross sections (σ) in the energy range 45<E<205 GeV are presented. We see no evidence for the anomalous sharp rise in σν¯σν reported by earlier authors. The neutrino cross section rises linearly with energy and with σE about 18% smaller than other measurements below 10 GeV. The average antineutrino slope at 55 GeV is consistent with measurements at low energy; however, a (20 ± 10)% increase is indicated over our energy range.

Normalized Small Y Cross-Sections for Neutrinos and anti-neutrinos at High-Energy

Barish, B.C. ; Bartlett, J.F. ; Bodek, A ; et al.
Phys.Rev.Lett. 39 (1977) 741, 1977.
Inspire Record 5717 DOI 10.17182/hepdata.50114

We present results on flux-normalized neutrino and antineutrino cross sections near y=0 from data obtained in the Fermilab narrow-band beam. We conclude that values of σ0=dσdy|y=0 are consistent with rising linearly with energy over the range 45<~Eν<~20.5 GeV. The separate averages of ν and ν¯, each measured to 4%, are equal to well within the errors. The best fit for the combined data gives σ0E=(0.719±0.035)×10−38 cm2/GeV at an average Eν of 100 GeV.

Measurement of Rates for Muonless Deep Inelastic Neutrino and anti-neutrino Interactions

Aubert, Bernard ; Benvenuti, A.C. ; Cline, D. ; et al.
Phys.Rev.Lett. 32 (1974) 1457, 1974.
Inspire Record 1123 DOI 10.17182/hepdata.21890

Relative rates for deep inelastic neutrino and antineutrino scattering without a finalstate muon have been measured. For neutrinos the result is Rν=σ(νμ+nucleon→νμ+hadrons)σ(νμ+nucleon→μ−+hadrons)=0.11±0.05. The corresponding ratio for antineutrinos is Rν¯=0.32±0.09.

Further observation of muonless neutrino-induced inelastic interactions.

Aubert, Bernard ; Benvenuti, A.C. ; Cline, D. ; et al.
Phys.Rev.Lett. 32 (1974) 1454-1457, 1974.
Inspire Record 882 DOI 10.17182/hepdata.21934

We report here additional positive results of a search for muonless neutrino- and anti-neutrino-induced events using an enriched antineutrino beam and a muon identifier of relatively high geometric detection efficiency. The ratio of muonless to muon event rates is observed to be R=0.20±0.05. We observe no background derived from ordinary neutrino or antineutrino interactions that is capable of explaining the muonless signal.
