Comparisons of Deep Inelastic e p and e n Cross-Sections

Bodek, A. ; Breidenbach, M. ; Dubin, D.L. ; et al.

Phys.Rev.Lett. 30 (1973) 1087, 1973.

Inspire Record 83716 DOI 10.17182/hepdata.21415

Cross sections for inelastic scattering of electrons from hydrogen and deuterium were measured for incident energies from 4.5 to 18 GeV, at scattering angles of 18°, 26°, and 34°, and covering a range of squared four-momentum transfers up to 20 (GeVc)2. Neutron cross sections were extracted from the deuterium data using an impulse approximation. Comparisons with the proton measurements show significant differences between the neutron and proton cross sections.

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.

The Ratio of Deep - Inelastic e-n to e-p Cross-Sections in the Threshold Region

Bodek, A. ; Dubin, D.L. ; Elias, J.E. ; et al.

Phys.Lett.B 51 (1974) 417-420, 1974.

Inspire Record 91646 DOI 10.17182/hepdata.27946

We report measurements of the ratio of the deep-inelastic electron-neutron to electron-proton differential cross sections in the threshold ( ω <3) region. The ratio was found to scale and to decrease monotically with decreasing ω . No violation of the quark model lower bound of 0.25 was observed in the ratio.

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.

Inclusive Hadron Production in Inelastic Muon-Proton Scattering at 150-GeV/c.

Phys.Rev.Lett. 35 (1975) 1483-1486, 1975.

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.

Inelastic Muon-Proton Scattering: Multiplicity Distributions, and Prong Cross-Sections

del Papa, C. ; Dorfan, David E. ; Flatte, Stanley M. ; et al.

Phys.Rev.D 13 (1976) 2934, 1976.

Inspire Record 108053 DOI 10.17182/hepdata.24754

In a streamer-chamber experiment at the Stanford Linear Accelerator Center, we observed hadron production in inelastic collisions of 14-GeV positive muons in a liquid hydrogen target. We report on the experiment, the analysis, and the resulting cross sections for hadronic prongs as well as the charged-hadron multiplicity distributions.

Properties of Inclusive Hadron Spectra in Muon Nucleon Scattering at 150-GeV/c

Anderson, H.L. ; Bharadwaj, V.K. ; Booth, N.E. ; et al.

Phys.Rev.Lett. 36 (1976) 1422, 1976.

Inspire Record 3759 DOI 10.17182/hepdata.3268

We have studied muon-produced hadrons from a deuterium target. The structure functions and the charge ratios are reported for neutrons; the transverse momentum and azimuthal distributions are reported for deuterons. The structure function for the neutron is similar to that of the proton. The charge ratio of produced hadrons follows the expectation of a simple spin-½ quark model. Transverse-momentum results agree with those at lower energy and are similar to those from hadron-hadron interactions. No azimuthal anisotropy is seen.
