The Exclusive Channel pi- pi- pi+ p in pi- p Interactions at 147-GeV/c.

Fong, D. ; Heller, M. ; Shapiro, A.M. ; et al.
Nuovo Cim.A 34 (1976) 659-671, 1976.
Inspire Record 112629 DOI 10.17182/hepdata.37618

The results of a study of the reaction π-p→π-π-π+p at2 147 GeV/c carried out at the Fermilab Proportional Wire 30″ Bubble Chamber Hybrid Spectrometer are reported. More than 92% of the cross-section ((670±41) μb) for this reaction is contained in those for proton and pion diffraction dissociation. The cross-sections for pion diffraction events with three-pion invariant mass in given regions are in agreement with values obtained by extrapolation of fits to data at lower incidentpion momenta. ρ0π- events make an important contribution in the A1 and A2 mass regions, and the data are consistent with contributions from f0π- in the A3 mass region. The cross-section for proton diffraction events is in agreement with a smooth extrapolation of the data at lower momentum.

K0(L) p Charge Exchange Scattering from 550-MeV/c to 1000-MeV/c

Edelstein, R.M. ; Fisk, H.E. ; Joseph, P. ; et al.
Phys.Rev.D 14 (1976) 702-707, 1976.
Inspire Record 115726 DOI 10.17182/hepdata.24674

Employing a neutral kaon beam at the Argonne Zero Gradient Synchrotron, a high-resolution magnetic spectrometer, and a neutron detector, differential cross sections have been obtained in the forward direction [0.045<|t|<0.18 (GeV/c)2] for the reaction KL0p→K+n. Previous studies of the time-reversed process in deuterium, K+d→K0p(p), have not yielded direct cross-section measurements in the forward direction because there is an inhibition of the non-spin-flip process in deuterium due to the Pauli exclusion principle. Nevertheless, our data are in agreement with the extracted free-neutron cross sections of deuterium studies as determined from the impulse and closure approximations.

We present results from a measurement of the differential cross sections for Σ−p, Ξ−p, and π−p elastic scattering at 23 GeV/c. We have collected samples of 6200 Σ−p events, 67 Ξ−p events, and 30 000 π−p events in the interval 0.10<|t|<0.23 (GeV/c)2.

Measurement of Medium-Energy alpha-Proton Elastic Scattering Beyond the First Minimum Region

Berger, J. ; Duflo, J. ; Goldzahl, L. ; et al.
Phys.Rev.Lett. 37 (1976) 1195-1198, 1976.
Inspire Record 116144 DOI 10.17182/hepdata.21086

The α-proton elastic scattering has been measured with α particles at equivalent incident proton energies of 438, 648, and 1036 MeV. A structure is observed at the position where a second minimum is expected in the differential cross section. Comparison with improved versions of the Glauber model are presented.

Multi-Pion and Multistrange Particle Photoproduction Off Neutrons Up to 5.3-GeV

The AACHEN-BONN-HAMBURG-HEIDELBERG-MUNICH collaboration Benz, P. ; Braun, O. ; Kiesling, Christian M. ; et al.
Nucl.Phys.B 115 (1976) 385-410, 1976.
Inspire Record 114867 DOI 10.17182/hepdata.37294

In a study of photoproduction at photon energies up to 5.3 GeV in a deuterium bubble chamber the reactions γ n→p π + π − π − and γ n→p π + π − π − π 0 were analyzed. In these reactions production of the resonances Δ ++ , Δ 0 , ϱ 0 , ω and A 2 − was observed. Photoproduction of strange particles was investigated and cross sections for the reactions γ n→ Λ K + π − , Σ − K 0 π + , pK − K 0 , Λ K 0 π + π − and Λ K + π − π 0 are presented. Production of Σ − (1385) and K ∗0 (890) was observed.

Cross-Sections and Charged Multiplicity Distributions for $\pi^- p$ and $K^- p$ Interactions at 147 GeV/c.

Fong, D. ; Heller, M. ; Shapiro, A.M. ; et al.
Nucl.Phys.B 102 (1976) 386-404, 1976.
Inspire Record 112604 DOI 10.17182/hepdata.36057

The results presented in this paper were obtained from a 105 000 frame exposure of the FNAL Hybrid Proportional Wire Chamber-30 inch Bubble Chamber System, in a tagged beam of 147 GeV/ c negative particles. Elastic, total and topological cross sections were obtained for both π − p and K − p interactions. Comparisons with other data, taken with various beam particles over large momentum intervals, show good agreement with KNO scaling, and similarity in the scaling behavior of σ n for the different beam particles.
