Absolute inclusive cross sections for\(\bar pp\) interactions at 7.3 GeV/c are given. The data cover prong cross sections,V0, γ production and inclusive charged particle (p/π) production. Separation has been made into annihilation and non-annihilation components. Inclusive π+, π− production in the processes of\(\bar pp\) annihilation and non-annihilation are compared with simple quark models.

Cross-Section Measurement for Nonstrange Final States and Single Pion Production in pi+ p Interactions at 3.6-GeV/c

Macnaughton, J. ; Butler, W.R. ; Coyne, D.G. ; et al.
Phys.Rev.D 15 (1977) 1832-1845, 1977.
Inspire Record 124169 DOI 10.17182/hepdata.24652

Cross sections are presented for all final states without strange-particle production. Contributions to single-pion production are found from (i) Δ(1238)π, (ii) ρ+p, (iii) nucleon diffractive dissociation into Nπ, (iv) N*(1688)π+, and (v) "phase space." Processes (i), (ii), and (iii) are studied in some detail taking into account overlaps between the various subchannels.

Antilambda production is studied inK−p interactions at 32 GeV/c. Both total and differential cross sections are presented. The inclusive\(\bar \Lambda \) production cross section amounts to 109±7 μb. A remarkable energy dependence is observed, σ(\(\bar \Lambda \)) increasing by a factor of four between 14.3 and 32 GeV/c. Thep⊥2 distribution exhibits an exponential fall-off with a slope of 3.3±0.2 (GeV/c)−2. Most of the\(\bar \Lambda \)'s are emitted in the forward hemisphere. The invariantx distribution increases between 14.3 and 32 GeV/c. Data are presented for\(\bar \Lambda \) production inK-p→Λ\(\bar \Lambda \)+XK-p→\(\bar \Lambda \)Kn+X, andK-p→\(\bar \Lambda \)p+X.

Single-pion production in k+ p interactions at 4.6 gev/c

Fu, C. ; Macnaughton, J. ; Trilling, G.H. ;
Nucl.Phys.B 28 (1971) 528-540, 1971.
Inspire Record 68682 DOI 10.17182/hepdata.33570

A study of K + p interactions at 4.6 GeV/ c leading to single-pion production is presented. Cross sections for the final states KΔ, K ∗ (891)p, K ∗ (1420)p are given. Comparison of the results of this study with published K − p and K − n data at the same momentum indicates that corresponding K − cross sections are significantly smaller, but other features such as momentum transfer distributions and density matrix elements are very similar.

Inclusive Production of Strangeness $S = \pm 1$ Vector and Tensor Resonances on $K^- P$ Interactions at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Arestov, Yu. ; Borovikov, A. ; Kozlovsky, E. ; et al.
Z.Phys.C 6 (1980) 101-108, 1980.
Inspire Record 154719 DOI 10.17182/hepdata.11053

We present final results on the inclusive production of the\(\bar K^{*0} (890)\),K*−(890),K*0(890),K*−(890),K*−(1420), and\(\bar K^{*0} (1420)\) resonances inK−p interactions at 32 GeV/c. Total cross sections and invariantx-distributions are determined. Inclusive cross sections of\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) amount to ≃4 mb each, of\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (1420)\) to ≃1 mb and ofK*0(890) to ≃0.8 mb. These values are in agreement with additive quark model predictions. All strangenessS=−1 resonances are predominantly produced in the forward hemisphere, the tensor mesons being more peripherally produced than the vector ones. The\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) density matrix elements andt-distributions are obtained. The unnatural spin-parity exchange contribution to inclusive\(\bar K^{*\underset{\raise0.3em\hbox{$\smash{\scriptscriptstyle-}$}}{o} } (890)\) production amounts to ≳60% at |t|<0.4 GeV2 and decreases with increasing |t|. Whenever relevant, a comparison is also made with available data at other energies.

SPIN - PARITY ANALYSIS OF THE (p pi+ pi-) SYSTEM IN THE REACTION K- p ---> K- pi- pi+ p AT 10-GeV/c, 14.3-GeV/c AND 16-GeV/c

The Aachen-Berlin-CERN-London-Vienna collaboration Otter, G. ; Rudolph, G. ; Wieczorek, H. ; et al.

Inspire Record 6590 DOI 10.17182/hepdata.42920

A partial-wave analysis of the diffractively produced p π + π − system has been performed for the reaction K − p→K − (p π + π − ) at 10, 14.3 and 16 GeV/ c using the isobar model. For p π + π − masses below 1.6 GeV, the system can be described by the states with spin-parity 1 2 + and 3 2 − . The dominant state is the 3 2 − S-wave Δπ . No evidence for resonance production can be found here. For higher masses, the states 5 2 + and 5 2 − are present in addition. The 5 2 − constitutes a violation of the Gribov-Morrison rule and its mass shape is consistent with being the D 15 N ∗ (1670) resonance. The peak in the p π + π − mass spectrum at 1.7 GeV cannot be explained by one single spin-parity state. A comparison of the diffractive reaction pomeron + p → p ππ with the formation experiment π p → N ππ is made.
