A Comparison of K+- n Charge Exchange Reactions at 8.5-GeV/c and 13-GeV/c

Gilchriese, M.G.D. ; Dunwoodie, W.M. ; Fieguth, T.H. ; et al.
Phys.Rev.Lett. 40 (1978) 6, 1978.
Inspire Record 120363 DOI 10.17182/hepdata.20886

The cross sections for the line-reversed reaction pairs K+n→K0p and K−p→K¯0n, and K+p→K0Δ++ and K−n→K¯0Δ− have been determined with high statistics and good relative normalization at 8.36 and 12.8 GeV/c in a spectrometer experiment at Stanford Linear Accelerator Center. The cross sections for the K+-induced reactions are larger than for the K−, contrary to the expectations of weakly-exchange-degenerate Regge-pole models. The ratio of the reaction cross sections is about the same as at lower energies and shows little change with momentum transfer.

Differential Cross-Sections for the Reactions K- p --> anti-K0 n, K- p --> anti-K0 Delta0, and K+ p --> K0 Delta++ at 13-GeV/c

Brandenburg, G.W. ; Carnegie, R.K. ; Cashmore, R.J. ; et al.
Phys.Rev.D 15 (1977) 617, 1977.
Inspire Record 110057 DOI 10.17182/hepdata.24603

Differential cross sections for the reactions K−p→K¯0n, K−p→K¯0Δ0, and K+p→K0Δ++ in the region 0<|t|<1.2 GeV2 are presented from a wire-spark-chamber spectrometer experiment performed in a 13-GeV/c separated beam. The results are based on 20 000 Δ++ events, 4600 Δ0 events, and 8500 n events. The line-reversed pair of Δ reactions is used to test Regge exchange degeneracy and an SU(3) sum rule. The energy dependence of all three reactions is studied by comparison with other experiments.

Hadron-Proton Elastic Scattering at 50-GeV/c, 100-GeV/c and 200-GeV/c Momentum

Akerlof, C.W. ; Kotthaus, R. ; Loveless, R.L. ; et al.
Phys.Rev.D 14 (1976) 2864, 1976.
Inspire Record 3655 DOI 10.17182/hepdata.24693

Elastic scattering of hadrons on protons has been measured at momenta of 50, 100, and 200 GeV/c. The meson-proton scattering is found to be independent of momentum and meson type for −t>0.8 (GeV/c)2. The momentum dependence of the pp dip at −t=1.4 (GeV/c)2 was investigated. Slope parameters are given.

The differential cross section for π±, K±, and p± on hydrogen have been measured in the range 0.07<−t<1.6 (GeV/c)2. The dependence on momentum, momentum, transfer, and particle type are discussed.

A SPARK CHAMBER MEASUREMENT OF THE REACTIONS PI+- P ---> RHO+- P AT 15-GEV/C

Pratt, J.C. ; Kaune, W.T. ; Lakin, W.L. ; et al.
Phys.Lett.B 41 (1972) 383, 1972.
Inspire Record 73430 DOI 10.17182/hepdata.28236

A new method, using spark chambers, for the study of the reactions π ± + p → ϱ ± + p is described. The charged pion and both γ rays from the π ± decay are detected. Differential and integrated cross sections σ π + =50 ± 9 μ b, σ π − =47 ± 9 μ b) for 0.0 ⩽| t |⩽1. (GeV/ c ) 2 and a laboratory momentum ( p Lab ) of 15 GeV/c are presented. The momentum dependence of σ γ ± is well fitted from 2.7 to 16 GeV/c by σ = K p Lab − with n γ + = 1.80 ± 0.80 and n γ − = 1.87 ± 0.15.
