Results are presented of measurements of the polarisation parameter for the reaction π−p→π°n : π°→γγ at 22 incident momenta in the resonance region. These results are generally in agreement with those of previous measurements and in qualitative agreement with predictions of phase shift analyses.

Single Particle Inclusive Spectra of Charged Particles in anti-p p Interactions at 22.4-GeV/c

The Alma Ata-Dubna-Helsinki-Kosice-Moscow-Prague collaboration Boos, E.G. ; Samoilov, V.V. ; Takibaev, Zh.S. ; et al.
Nucl.Phys.B 121 (1977) 381-392, 1977.
Inspire Record 109633 DOI 10.17182/hepdata.35465

The inclusive spectra for p p collisions at 22.4 GeV/ c are investigated. We show that the transverse momentum distributions resemble those in high-energy pp interactions and discuss the influence of annihilation processes on the p T 2 distributions. The invariant inclusive cross section for pions in the central region is found to be 28 ± 1 mb. A charge asymmetry is indicated by the y ∗ spectrum in the central region, the asymmetry parameter having the value 0.15 ± 0.01. Finally, we estimate the upper limit of the diffraction dissociation of the beam particle to be 3.68 −0.15 +0.45 mb.

Differential Cross-Section Measurements in $\pi^{-}$p Charge Exchange Scattering from 620 to 2730-MeV/c

Brown, Robert M. ; Clark, A.G. ; Davies, J.K. ; et al.
Nucl.Phys.B 117 (1976) 12-49, 1976.
Inspire Record 110001 DOI 10.17182/hepdata.8341

Results are presented of differential cross-section measurements for the reaction π − p→ π 0 n; π 0 → γγ at 22 incident pion momenta between 618 and 2724 MeV/ c . The results are in good agreement with those of other experiments. They represent the first comprehensive set of high statistics measurements of the π − p charge-exchange differential cross section at closely spaced momenta in the resonance region.

The Reactions K- p --> pi-+ Sigma+- at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Massaro, G.G.G. ; Barlag, S. ; de Groot, A.J. ; et al.
Phys.Lett.B 66 (1977) 385-389, 1977.
Inspire Record 110532 DOI 10.17182/hepdata.27595

We present differential cross sections and the Σ + polarization for the reactions K − p → π ∓ Σ ± using data from a high statistics bubble chamber experiment at 4.2 GeV/ c incident momentum. The statistical level allows a detailed analysis of these reactions over the whole t range. Several significant structures are observed. Comparisons are made with SU(3)-related reactions; for backward production of π − Σ + such a comparison shows good evidence for Δ exchange. The exotic forward peak in K − p → π + Σ − is definitely confirmed.

K- p --> Lambda0 Or Sigma0 Vector Meson at 3.1-GeV/c-3.6-GeV/c

Lyons, L. ; Cooper-Sarkar, Amanda M. ; Clark, A.G. ;
Nucl.Phys.B 125 (1977) 207-242, 1977.
Inspire Record 125082 DOI 10.17182/hepdata.35373

We present data on the five final states Λω, Λφ, Λϱ 0 , Σ 0 ⊘ and Σ 0 ϱ 0 produced in 3.1–3.6 GeV/ c K − p interactions. These data are from a bubble chamber experiment with 18 events/μb. For all reactions the data consist of the overall and differetial cross sections, and the hyperon polarisation and the vector meson's density matrix elements as a function of momentum transfer. For Λω and Λ⊘, an almost complete amplitude analysis is performed in several regions of momentum transfer. The data are examined from the point of view of various exchange models.
