Eichten, T. ; Faissner, H. ; Hasert, F.J. ; et al.
Phys.Lett.B 46 (1973) 274-280, 1973.
Inspire Record 84484 DOI 10.17182/hepdata.28054

The v and v nucleon total cross-sections have been determined as a function of energy using a sample of 2500 v and 950 v event. The results are compared with predictions of scaling and charge symmetry hypotheses.

MUON PROTON DEEP INELASTIC SCATTERING

Entenberg, A. ; Jostlein, H. ; Kostoulas, I. ; et al.
Phys.Rev.Lett. 32 (1974) 486, 1974.
Inspire Record 80537 DOI 10.17182/hepdata.21303

We have measured muon-proton deep inelastic scattering in the range 0.4<q2<3.6 (GeV/c)2. The data are consistent with muon-electron universality, and if the ratio ρ=νW2(μ−p)νW2(e−p) is fitted with the form ρ=N(1+q2Λ2)−2, we obtain N=0.997±0.043 and Λ−2=+0.006±0.016 (GeV/c)2. This result establishes that |Λ|>~5.1 GeV/c with 95% confidence.

Production of pi0 Mesons in K+ p Interactions at 8.2-GeV/c

Bartke, J. ; Eskreys, A. ; Figiel, J. ; et al.
Acta Phys.Polon.B 5 (1974) 689, 1974.
Inspire Record 90280 DOI 10.17182/hepdata.51679

Experimental results on $\pi^0$ production in $K^+$p interactions at 8.2 GeV/$c$ incident momentum are presented. Average $\pi^0$ multiplicities for given prong numbers are evaluated. They are consistent both with the corresponding results for pp interactions at 12 GeV/$c$ chosen for comparison because they have the same average prong number) and with a model where total multiplicity distributions are calculated from the Czyżewski--Rybicki formula and the charge branching ratios from the statistical model. Some averages over the $\pi^0$ momentum distribution are also evaluated. In particular it is found that $\pi^0$-s produced in two prong interactions go predominantly forward.

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.

Approximate Scaling of Multiplicity Distributions as a Function of Missing Mass

Barshay, S. ; Engelmann, R. ; Kafka, T. ; et al.
Phys.Rev.Lett. 32 (1974) 1390, 1974.
Inspire Record 1032 DOI 10.17182/hepdata.21933

Data from p+p→p+X at 102, 205, and 405 GeV and from π−+p→p+X at 205 GeV exhibit an approximate scaling property in the charged-prong multiplicity distributions as a function of the missing mass for the range 5<~MX<~13 GeV.

Observation of single pion production by a weak neutral current.

Barish, S.J. ; Cho, Y. ; Derrick, M. ; et al.
Phys.Rev.Lett. 33 (1974) 448, 1974.
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.

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 Large Transverse Momentum Muons Directly Produced by 300-GeV Protons

Boymond, J.P. ; Mermod, R. ; Piroue, P.A. ; et al.
Phys.Rev.Lett. 33 (1974) 112, 1974.
Inspire Record 1236 DOI 10.17182/hepdata.43753

We have observed muons produced directly in Cu and W targets by 300-GeV incident protons. We find a yield of muons which is approximately a constant fraction (0.8·10−4) of the pion yield for both positive and negative charges and for transverse momenta between 1.5 and 5.4 GeV/c.

Muon-Deuterium Deep Inelastic Scattering

Kim, I.J. ; Entenberg, A. ; Jostlein, H. ; et al.
Phys.Rev.Lett. 33 (1974) 551, 1974.
Inspire Record 1427 DOI 10.17182/hepdata.21238

We have measured deep inelastic muon-deuteron scattering in the range 0.4<Q2<3.4 and 1.6<ν<5.6 GeV. We have extracted the neutron structure function and find that νW2n differs significantly from νW2p, as also found in e−d scattering. To compare μ−d and e−d scattering we form the ratio r(Q2)=(νW2)μd(νW2)ed=N(1+Q2Λ2)−2 and find N=0.925±0.038 and 1Λ2=−0.019±0.016.

Inspire Record 102517 DOI 10.17182/hepdata.3284

Inclusive hadron production in muon-proton inelastic scattering has been measured for q2>0.5 (GeV/c)2 and 10<ν<135 GeV. The results are presented in the form of the transverse momentum distribution of charged hadrons and the hadron invariant structure function F(x′). Results are given for different regions of q2 and s.
