REACTION K+ P ---> K N PI PI AT 4.27-GeV/c INCIDENT MOMENTUM

Gelfand, N.M. ; Lasinski, B. ; Leary, P. ; et al.
Phys.Rev.D 26 (1982) 2973-2978, 1982.
Inspire Record 184512 DOI 10.17182/hepdata.23895

The cross sections for K+p interactions at a center-of-mass energy of 3 GeV (4.3 GeV/c incident momentum) have been determined for the K+pπ+π−, K0pπ+π0, and K0π+π+n final states. The shape of the differential cross section dσdt′ for the quasi-two-body final state K*0(890)+Δ++(1236) is not a single exponential. Characteristics of the low-mass Kππ and pππ enhancements are discussed.

From a study of 8-GeV/c π−p interactions, the various two-pion and four-pion decay channels available to the g− meson have been investigated. Our results indicate that the dominant 4π decay modes involve intermediate ρ and ω production without significant A2 formation.

ELASTIC SCATTERING AND PARTICLE PRODUCTION IN TWO PRONG PI- P INTERACTIONS AT 8-GEV/C

Inspire Record 182974 DOI 10.17182/hepdata.23945

Results of a high-statistics study of elastic scattering and meson resonances produced by π−p interactions at 8 GeV/c are presented. Large statistics and small systematic errors permit examination of the complete kinematic region. Total differential cross sections are given for ρ0,−, f0, g0,−, Δ±, Δ0, and N* resonances. Spin-density matrix elements and Legendre-polynomial moments are given for ρ, f, and Δ resonances. The results for ρ0 and f0 resonances are compared with the predictions of a Regge-pole-exchange model. Properties of the above resonances are compared and discussed. In particular, we present evidence that the ρ0 and f0 production mechanisms are similar. The similarity of the g0 t distribution to that of the ρ0 and f0 suggests a common production mechanism for all three resonances.

THE REACTION ANTI-P P ---> DELTA (1236) ANTI-DELTA (1236) AT BEAM MOMENTA OF 7.23-GEV/C AND 12.0-GEV/C

Van Apeldoorn, G.W. ; Harting, D. ; Holthuizen, D.J. ; et al.
Z.Phys.C 12 (1982) 95-98, 1982.
Inspire Record 179937 DOI 10.17182/hepdata.16432

The reactionp→Δ(1236)\(\bar \Delta \)(1236) is studied at 7.23 GeV/c and at 12GeV/c in terms of the OPE model of Wolf. Good agreement between the model and experimental data is found for the mass andt distributions whereas for decay angular distributions the agreement is less satisfactory. A modified model, allowing for a spin orbit coupling, gives good agreement also for the angular distribution.

DECAY OF B MESONS INTO CHARGED AND NEUTRAL KAONS

Inspire Record 180612 DOI 10.17182/hepdata.27749

Data on inclusive kaon production in e+e− annihilations at energies in the vicinity of the ϒ(4S) resonance are presented. A clear excess of kaons is observed on the ϒ(4S) compared to the continuum. Under the assumption that the ϒ(4S) decays into BB¯, a total of 3.38±0.34±0.68 kaons per ϒ(4S) decay is found. In the context of the standard B-decay model this leads to a value for (b→c)(b→all) of 1.09±0.33±0.13.

A STUDY OF THE REACTION K- P ---> K- PHI P AT 8.25-GeV/c

The dissociation of a K− into the K−ϕ system is studied at 8.25 GeV/c. The cross-section for K−ϕp production is (27±2) μb. All the expected properties of diffraction are found (mass spectrum, mass-slope correlation, 1+S wave dominance). There is also an indication of the Kϕ decay mode of a 2− resonance in theL region.

KAON SCATTERING AND CHARGED SIGMA HYPERON PRODUCTION IN K- P INTERACTIONS BELOW 300-MEV/C

Ciborowski, J. ; Gwizdz, J. ; Kielczewska, D. ; et al.
J.Phys.G 8 (1982) 13-32, 1982.
Inspire Record 179889 DOI 10.17182/hepdata.38531

In an experiment on K--proton interactions in a hydrogen bubble chamber, the cross sections and angular distributions have been studied for elastic and charge-exchange scattering, and charged sigma hyperon production in the momentum range 90-300 MeV/c. Good agreement is found with previous cross sections except for the charge-exchange channel where the new values are 60% larger. The production distributions of the charged sigma hyperons and the polarisation of the Sigma + hyperon clearly indicate that P waves are present down to about 150 MeV/c, much lower than previously reported.

STUDY OF THE REACTION K- P ---> PHI PHI LAMBDA AT 8.25-GeV/c

In a high statistics bubble chamber study the reaction K − p → φφΛ is detected with a cross section of 0.7±0.2 μ b. The ratio of φφ production in K − and π − induced reactions is found to be ∼5; this is about ten times smaller than the ratio for the corresponding single φ production reactions.
