Exclusive Reactions in $\bar{p} p$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Jabiol, M.A. ; Denegri, D. ; Louedec, C. ; et al.
Nucl.Phys.B 183 (1981) 330-348, 1981.
Inspire Record 155103 DOI 10.17182/hepdata.34313

The cross sections of several exclusive reactions in p p interactions are given. In the channels p p → p p π + π − and p p → p p 2π + 2π − which dominate the interactions, the single and double diffractive dissociations are analysed and compared to the results obtained with K ± p interactions at the same energy, pp and p p interactions at other energies. The test of factorization at the p → p π + π − vertex is well verified. The process p p → Δ ++ Δ ++ is studied and the cross sections of Δ ++ , Δ ++ , ϱ 0 and f 0 production are also given.

A Study of the Reactions $K^- p \to \Lambda \pi^0$, $\Lambda \eta$, $\Lambda \eta^\prime$ at 8.25-{GeV}/$c$ Incident $K^-$ Momentum

Nucl.Phys.B 183 (1981) 269-294, 1981.
Inspire Record 155276 DOI 10.17182/hepdata.34295

Differential cross sections and polarizations are presented for the reactions K − p → Λπ 0 , Λη , Λη ′ at 8.25 GeV/ c incident K − momentum. The data, which come from a high statistics experiment in the CERN 2 m bubble chamber, are compared with previous experimental results on the same reactions and with current theoretical ideas.

Measurements of the Total Cross-sections of $\Sigma^-$ and $\Xi^-$ on Protons and Deuterons Between 74-{GeV}/$c$ and 137-{GeV}/$c$

Inspire Record 155257 DOI 10.17182/hepdata.7853

The Σ − p and Σ − d total cross sections have been measured to a statistical accuracy of ±1% and ±0.5%, respectively, at five momenta from 74.5 to 136.9 GeV/ c , using the hyperon beam at the CERN SPS. The Ξ − p and Ξ − d total cross sections have also been measured to the same statistical accuracy at 101.5 and 133.8 GeV/ c . The systematic uncertainty at each momentum is estimated to be of the order of ±0.5%. The hyperon-nucleon cross sections are shown to be rising with energy, and the data are compared with various phenomenological models.

INELASTIC ELECTRON PHOTON SCATTERING AT MODERATE FOUR MOMENTUM TRANSFERS

Phys.Lett.B 99 (1981) 287-291, 1981.
Inspire Record 155594 DOI 10.17182/hepdata.27125

We present new high statistics data on hadron production in photon-photon reactions. The data are analyzed in terms of an electron-photon scattering formalism. The dependence of the total cross section of Q 2 , the four-momentum transfer squared of the scattered electron, and on the mass W of the hadronic system is investigated. The data are compared to predictions from Vector-Meson Dominance and the quark model.
