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.

Precision Measurement of n p Charge Exchange Cross-Section at 647-MeV

Evans, M.L. ; Glass, G. ; Hiebert, J.C. ; et al.
Phys.Rev.Lett. 36 (1976) 497-500, 1976.
Inspire Record 112959 DOI 10.17182/hepdata.21088

The differential cross section for n−p elastic scattering in the angular region 145°<θc.m.<180° has been measured with high statistical accuracy using the monoenergetic neutron beam at Clinton P. Anderson Meson Physics Facility. The results differ significantly from previous Dubna and Princeton-Pennsylvania Accelerator results but agree reasonably well with recent Saclay data except at extreme backward angles.

Polarization in p p Elastic Scattering at Large Four Momentum Transfers

Bryant, G.W. ; Corcoran, M. ; Crittenden, R.R ; et al.
Phys.Rev.D 13 (1976) 1-4, 1976.
Inspire Record 113034 DOI 10.17182/hepdata.24788

New results are presented from the continuation of an experiment designed to study the polarization in elastic p−p scattering at large four-momentum transfers. A high-intensity unpolarized proton beam of momentum 12.3 GeV/c was incident on a propanediol polarized proton target and both final-state protons were detected and momentum-analyzed in multiwire proportional chamber spectrometers. The measurements spanned the t range 1.5<|t|<6.2 (GeV/c)2. The results are discussed in the framework of optical, exchange, and parton models.

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.

Inspire Record 114489 DOI 10.17182/hepdata.21070

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.

Inclusive Single Particle Production at 90-Degrees in the Center-Of-Mass System for Nuclear Targets and 28.5-GeV/c Incident Protons

Becker, U. ; Burger, J. ; Chen, M. ; et al.
Phys.Rev.Lett. 37 (1976) 1731-1734, 1976.
Inspire Record 115394 DOI 10.17182/hepdata.21074

The invariant cross section for the inclusive production of π+, π−, K+, K−, p, and p¯ is presented for proton-nucleon interactions at plab=28.5 GeV/c. Beryllium, titanium, and tungsten targets were used and the yields were extrapolated to A=1 using the power law σ∼Aα. The exponent α increases with pT, except for protons. The pT dependence of the cross sections is compared with a simple fireball model.

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.

A Study of Resonance Production in the Reaction K+ p --> K0 p pi+ from 3 to 16-GeV/c

Carney, J.N. ; Colley, D.C. ; James, M.F. ; et al.
Nucl.Phys.B 107 (1976) 381-421, 1976.
Inspire Record 113912 DOI 10.17182/hepdata.35837

The reactions K + p → K ∗+ (890) p , K + p → K ∗+ (1420) p and K + p → K 0 Δ ++ have been systematically studied for eleven incident momenta between 3.0 and 16.0 GeV/ c . Cross sections, differential cross sections and density matrix elements are presented. For K ∗ (890) production the contributions from natural and unnatural parity exchanges have also been separated into I = 0 and I = 1 components. Effective trajectories have been extracted in the case of natural parity exchange, and also for Δ ++ production.
