Inclusive and semi-inclusive distributions of γ's and π 0 's in the reactions K + p → γ + X and K + p → π 0 + X at 32 GeV/ c are presented and discussed. When compared to the inclusive π − production, the π 0 cross section is found to be significantly higher in low | x | and p T regions. The data are compared with other experiments and quark fusion model predictions.

Inclusive production of Δ ++ (1232) with >| t p, Δ ++>|<0.6 (GeV/ c ) 2 is studied in 32 GeV/ c K + p interactions. A systematic comparison with the reaction K + p→pX for >| t p,p>| < 0.6 (GeV/ c ) 2 is made. The production properties of the Δ ++ (1232), of associated π + , π − and K 0 production and of the recoiling system X 0 are investigated in detail. The polarization of the Δ ++ and the energy dependence of the total K + π − cross sections, determined by a Chew-Low extrapolation, are presented and discussed.

A Comparison of Inclusive $\rho^0$, $\rho^+$ and $\Omega$ Production in $K^+ P$ Interactions at 250-{GeV}/c

Inclusive data are presented on ϱ 0 ,ϱ + and ω produced in k + p interactions at 250 GeV/ c , for ϱ + and ω for the first time in K + p experiment. In the forward CM hemisphere, the ϱ + , ϱ 0 and ω differential production rates are equal within errors, and remarkably similar to muon-inelastic scattering data on ϱ 0 and ω at 280 GeV/ c .

Strangeness Suppression and Inclusive $\phi$ and $K^*$0 Production in $K^+ P$ Interactions at 250-{GeV}/c

We present inclusive ¶ and K *0 (892) cross sections and Feynman x -spectra in K + p collisions at 250 GeV/ c . In the K + fragmentation region, x > 0.2, the ratio of ¶ to K *0 (892) is used to estimate the strangeness suppression factor λ , with the result γ =0.17 ± 0.02 (stat ± 0.01 (syst). We see no evidence for an energy dependence of λ in the CM energy range 7.8 ≤ s ≤21.7 GeV.

Decay distributions in the reaction k+ p ---> k*0(1420) delta++ at 5 gev/c and quark model predictions

Eskreys, A. ; Malecki, P. ; Zalewski, K. ; et al.
Nucl.Phys.B 29 (1971) 587-600, 1971.
Inspire Record 68631 DOI 10.17182/hepdata.33559

Joint decay distributions have been studied in the reaction K + p → K ∗o (1420)Δ ++ at 5.0 GeV/ c in the transversity spin reference frame. Two alternative spin-parity assignments 2 + and 3 − for the K ∗ resonance have been considered and a comparison with the quark-model predictions has been made. The predictions of the quark model are equally well satisfied by the experimental results for both the 2 + and 3 − spin-parity assignments.

Study of the Inclusive Reactions $K^+ p \to p$ X and $K^+ p \to p K^0$ X at 32-{GeV}/$c$

The French-Soviet & CERN-Soviet collaborations Laurent, J. ; Dujardin, C. ; Grard, F. ; et al.
Nucl.Phys.B 149 (1979) 189-210, 1979.
Inspire Record 132914 DOI 10.17182/hepdata.34832

The inclusive production of protons with laboratory momentum less than 1.2 GeV/ c is studied in the reacion K + p → pX at 32 GeV/ c . A comparison with the 16 GeV/ c data shows ahat the total cross section remains practically constant while the structure function shows a clear energy dependence. The data are compatible with a tripls-Regge expansion and with factorization. About 40% of the events include a K 0 in the final state. The analysis of the K 0 pX sample indicates a sizeable contribution of beam fragmentation and abundant K 890 ∗ and Δ ++ production.

We present our final data on the production of the baryons p, Λ, Λ , Σ 0 , Σ 0 , Σ − , Σ + , Ω + , and of the baryon resonances Δ ++ (1232), Σ ∗± (1385), Σ ∗± (1385) in K + p interactions at 70 GeV/ c . Results are given on total and semi-inclusive cross sections, transverse momentum distributions and Feynman- x spectra. The data are compared with measurements at 32 GeV/ c and other energies. The predictions of the LUND fragmentation model for low- p T hadron-hadron collisions are examined and found to offer a reasonably successful description of the data.
