Study of Neutrino Proton Elastic Scattering in the GARGAMELLE Freon Experiment

Pohl, M. ; Welch, L. ; Dewit, M. ; et al.
Phys.Lett.B 72 (1978) 489-492, 1978.
Inspire Record 122236 DOI 10.17182/hepdata.48973

The cross section ratio of the elastic neutral current reaction ν p→ ν p to the quasi-elastic charged current reaction ν n→ μ − p has been measured in the kinematical region 0.3⩽ q 2 ⩽1.0 (GeV/ c ) 2 . The measured value is R M =0.17±0.08. Model dependent corrections are applied, especially for ν n→ ν n contamination, and the result is compared to various models.

Rho0 Production in 205-GeV/c p p Interactions

Singer, R. ; Fields, T.H. ; Hyman, L.G. ; et al.
Phys.Lett.B 60 (1976) 385-388, 1976.
Inspire Record 2818 DOI 10.17182/hepdata.6484

Inclusive and semi-inclusive ρ 0 production are studied in 205 GeV/ c pp interactions. The number of ρ 0 per inelastic event is 0.33 ± 0.06, so that (13 ± 2)% of the π − are products of ϱ 0 decay. The ρ 0 are found to be produced mainly near y = 0 and tend to have larger average transverse momentum than do pions.

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.

Observation of single pion production by a weak neutral current.

Barish, S.J. ; Cho, Y. ; Derrick, M. ; et al.

Inspire Record 89586 DOI 10.17182/hepdata.51354

In exposures of the Argonne National Laboratory 12-ft bubble chamber filled with hydrogen and deuterium to a neutrino beam, we have observed events consisting of (1) a single π+ meson originating in the liquid, and (2) a proton with an e+e− pair pointing to it. Only a small fraction of these events can be ascribed to known reactions such as np→nnπ+ and np→npπ0. The remaining events, which correspond to a signal of about 4.5 standard deviations, we ascribe to the reactions νp→νnπ+ and νpπ0.

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.
