A study of the reaction pi-minus + p ---> lambda + anti-lambda + n at 7 and 12 gev/c

Beusch, W. ; Fischer, W.E. ; Pepin, M. ; et al.
Phys.Lett.B 28 (1968) 211-214, 1968.
Inspire Record 56830 DOI 10.17182/hepdata.29078

Over 100 unambiguous π − + p → Λ + Λ + n events have been observed in a magnet spark chamber. The data provide good evidence for peripheral production of Λ Λ and n Λ (via meson exchange) and against peripheral n Λ (double baryon exchange). No resonances in the Λ Λ system are observed. Angular distributions and Λ( Λ ) polarizations are analysed.

This article reports the results of a spark-chamber measurement of the reactions K−+p→K¯0+neutrals and K−+p→Λ0+neutrals with an incident kaon momentum of 7.7 GeV/c. The production cross sections for these reactions are measured to be 800±50 μb and 188±18 μb, respectively. The cross-section distributions d2σdPIIdP⊥ in the center-of-mass system with large momentum transfer are discussed in terms of a fireball model of production.

On $K_L$ - $K_S$ Regeneration in Copper

Bohm, A. ; Darriulat, P. ; Grosso, C. ; et al.
Phys.Lett.B 27 (1968) 594-598, 1968.
Inspire Record 1374884 DOI 10.17182/hepdata.69210

The transmission regeneration amplitude after a thick copper block has been measured. The quantity {∣ƒ(0)- overlineƒ(0)∣ }/{k} varies from 20.0 $\pm$ 1.4 mb at 2.75 GeV/c to 13.6 $\pm$ 1.2 mb at 7.25 GeV/c. Results are in agreement with optical model calculations in which real and imaginary parts of the amplitudes for single nucleon scattering are determined from forward dispersion relations and total cross-sections.

We have analyzed 2560 events in the final-state K O 1 K O 1 n produced in π − p interactions at 5, 7 and 12 GeV/ c . We observe the S ∗ (1070), f O and A 2 decaying into K O 1 K O 1 . Resonance parameters, cross sections, and branching ratios are given.

K+ P ELASTIC SCATTERING AT 3.5-GeV/c AND 5.0-GeV/c

Inspire Record 50048 DOI 10.17182/hepdata.37572

The elastic scattering of K+ mesons on protons is studied at 3.5 and 5 GeV/c. The total elastic cross-sections are found to be (4.36±0.36) mb and (3.82±0.41) mb respectively. The differential elastic cross-sections, which exhibit characteristic diffraction peaks, are fitted by dσ/dt=(dσ/dt)0eαt, giving α=(3.85±0.12) and (4.70±0.21) (GeV/c)−2 for the two momenta respectively, with |t|⪝0.65 (GeV/c)2. The results are compared to those at neighbouring energies, giving some support to the presence of a real part of the forward scattering amplitude. The diffraction peak shows definite shrinking with increasing momenta. The data are examined in the light of models for high-energy scattering.
