Charged Particle Multiplicity Distribution from 200-GeV pp Interactions

Charlton, G. ; Cho, Y. ; Derrick, M. ; et al.
Phys.Rev.Lett. 29 (1972) 515, 1972.
Inspire Record 73783 DOI 10.17182/hepdata.21430

From 2728 events of 205-GeV pp interactions found in 15 000 pictures taken with the 30-in. hydrogen bubble chamber at the National Accelerator Laboratory, a total cross section of 39.5±1.1 mb was measured. The mean charged-particle multiplicity for inelastic pp collisions was measured to be 7.65±0.17. The prong distribution from 2 to 22 prongs is broader than a Poisson distribution and has a width parameter f2−=〈n−(n−−1)〉−〈n−〉2=0.95±0.21.

Backward electron-deuteron scattering below 280 mev

Ganichot, D. ; Grossetete, B. ; Isabelle, D.B. ;
Nucl.Phys.A 178 (1972) 545-562, 1972.
Inspire Record 75366 DOI 10.17182/hepdata.8775

We measured the elastic and inelastic scattering of electrons on deuterium at 180° for four incident energies (70, 140, 210 and 280 MeV). The data were analysed with a technique allowing an accurate comparison between experiment and theory. We observed a good agreement for the inelastic data with the expected cross section, using the presently available models and nucleon form factors. The experimental elastic cross section is systematically larger than the predicted cross sections.

Study of the reaction anti-p n ---> anti-p pi- p at 7.0 gev/c

Nucl.Phys.B 43 (1972) 45-61, 1972.
Inspire Record 75088 DOI 10.17182/hepdata.32868

From a 3.5 ev/μb exposure of the BNL 80 inch chamber filled with deuterium to a 7.0 GeV/ c p beam we obtained 664 events in the channel p n → p π − p . The channel cross section is (1270 ± 110 60 ) μb. The final state is dominated by Δ (1230) production. The experimental data is well described by a one-pion exchange model with off-mass shell corrections.

The reactions $k^{+}d \to k^{+}d, k^{+}d \to k^{+}pn$ and $k^{+}d \to k^{0}pp$ at 3 Gev/$c$ with an investigation of $k^+n$ scattering

Inspire Record 75078 DOI 10.17182/hepdata.32864

As a partial result of an analysis of K + d interactions at 3 GeV/ c produced in the 81 cm Saclay bubble chamber, we present data on K + differential cross sections for the following reactions: K + d → K + d, K + d → K + pn, K + d → K 0 pp . A set of parameters describing the K + n elastic scattering has been obtained from a simulataneous fit, based on the Glauber model. to the three experimental differential cross sections and to the K + d total cross section, giving α n = 1.7 ± 0.5 GeV −2 for the slope α n of the differential cross section, and ρ n = −0.16 ± 0.3 for the ratio of the real to the imaginary part of the forward scattering amplitude. The D-wave function of the deuteron has been found to give a non-negligible contribution to the coherent reaction.

Production of the k- pi+ pi- n final state in k- d interactions at 5.5 gev/c

Davis, R. ; Ammar, R. ; Kropac, W. ; et al.
Nucl.Phys.B 44 (1972) 45-82, 1972.
Inspire Record 75079 DOI 10.17182/hepdata.32866

The reaction K − d → K − π + π − n p s was studied in a bubble chamber experiment. The cross section was measured to be 1.3 ± 0.2 mb. The final state is dominated by K ∗0 (890) , K ∗0 (1420) and Δ − (1236) production. Partial cross sections, differential cross sections and decay angular distributions of the K ∗0 (890) δ − (1236) final state were found to give good agreement with the predictions of Białas and Zalewski obtained from the quark model. The final state K − π + Δ − (1236) is analyzed by use of the Van Hove plot.

Study of the reaction k- p ---> anti-k n pi at 4.2 gev/c

Tiecke, H.G.J M. ; Crijns, F.J.G H. ; Heinen, P.M. ; et al.
Nucl.Phys.B 39 (1972) 596-615, 1972.
Inspire Record 75240 DOI 10.17182/hepdata.32931

Results are presented on effective-mass distributions, differentisl cross sections and longitudinal c.m. momentum distributions for the channels K − p → K − p π o , K o p π − and K − π + n , obtained from a sample of approximately 28 000 inelastic two-pronged interactions at 4.2 GeV/ c incident momentum. The results are in satisfactory agreement with the prediction of a generalized Veneziano-model corrected for (non-dual) π -and pomeron exchange. For the channel K − pπ o pomeron exchange contributes about 20% of the cross section. In the channel K − π + n the dual, pion and pomeron contributions are responsible for resp. 15%, 65% and 20% of the total cross section.

The total cross sections of 18.7 GeV Σ − hyperons on protons and deutrons have been measured to be 34.0 ± 1.1 mb and 61.3 + 1.4 mb, respectively. The derived Σ − -neutron cross section is 30.0 ± 1.2 mb.
