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.

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.

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.

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.

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.
