SMALL MOMENTUM TRANSFER K- p CHARGE EXCHANGE SCATTERING AT 30-GeV/c

The Serpukhov-Brussels-Annecy(LAPP) collaboration Binon, F. ; Lagnaux, J.P. ; Roosen, R. ; et al.
Nuovo Cim.A 64 (1981) 89-100, 1981.
Inspire Record 164179 DOI 10.17182/hepdata.49654

The\(K^ -p \to \bar K^0 n\) charge exchange differential cross-section has been measured at 30 GeV/c with high statistical accuracy and high angular resolution. The experiment was made at the IHEP 70 GeV accelerator, by using a hodoscope hadron calorimeter to detect KL0. The cross-section shows a dip at small |t|, which indicates a dominance of spin-flip amplitudes in ρ and A2 exchanges in thet-channel.

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.

Study of the Reaction K- p --> anti-K0 n at Momenta of 25-GeV/c and 40-GeV/c

The Serpukhov-CERN collaboration Apel, W.D. ; Bertolucci, E. ; Donskov, S.V. ; et al.
Nucl.Phys.B 129 (1977) 275, 1977.
Inspire Record 120460 DOI 10.17182/hepdata.35232

Measurements were made of the differential cross sections for the charge exchange of K − mesons on protons at momenta of 25 and 40 GeV/ c using a high-precision spectrometer with no magnetic field. In the range 5–40 GeV/ c the reaction cross section follows a power-law dependence p K − −1.52 . In the snall momentum transfer region (− t ⪅ m π 2 ) a minimum is observed, similar to that discovered at lower energies. The differential cross sections t = 0 are considerably less than those predicted by the Regge-pole model. The parameters of the effective trajectory are determined.

The K- p Charge Exchange and Elastic Scattering Reactions at 4.2-GeV/c

The Amsterdam-CERN-Nijmegen-Oxford collaboration Marzano, F. ; Toet, D.Z. ; Gavillet, P. ; et al.
Phys.Lett.B 68 (1977) 292, 1977.
Inspire Record 119361 DOI 10.17182/hepdata.48927

In this letter results are presented on the reactions K − p → K 0 n and K − p → K − p from a high statistics CERN 2-metre hydrogen bubble chamber exposure at 4.15 GeV/ c . The behaviour of the differential cross section as a function of four-momentum transfer shows remarkable similarities between the two reactions studied. From a comparison of our data with K + p elastic scattering at 4.27 GeV/ c we draw some conclusions concerning the magnitude of the contributing amplitudes.

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.

A Study of the Final States anti-K0 n, Lambda pi0 and anti-K0 Delta0 in K- p Interactions at 5-GeV/c and 8-GeV/c

Gallivan, J. ; Astbury, P. ; Jafar, J. ; et al.

Inspire Record 110114 DOI 10.17182/hepdata.35539

We present results on three reactions involving neutral final states which were studied in a magnet spark chamber system. These results are: (a) differential cross section with high statistics for K − p → K 0 n at 5 GeV /c (24 000 events) and at 8 GeV/ c (11 000 events) for t′ <2.0 (GeV/ c ) 2 ; (b) differential cross section and polarization for K − p → Λπ 0 (backward peak) at 5 GeV/ c for u ′ < 1.4 GeV/ c ) 2 ; and (c) differential cross section for K − p → K 0 Δ 0 (1232) at 5 GeV /c for t′ < 1.2 ( GeV /c) 2 . We compare our results with existing data and draw some phenomenological conclusions.

Line Reversal Breaking in K+- n Charge Exchange and K+- n --> K0 Delta (1236) at 4-GeV/c and 6-GeV/c

Phelan, J.J. ; Ambats, I. ; Meyer, W.T. ; et al.
Phys.Lett.B 61 (1976) 483-486, 1976.
Inspire Record 2871 DOI 10.17182/hepdata.27677

Differential cross sections for the line-reversed reaction pairs K + 0p → K o Δ ++ (1236), K − n → K ̄ o Δ − (1236) and K − p → K ̄ o n , K + n → K o p have been measured with good statistics at 4 and 6 GeV/ c . The line reversal breaking for the Δ (1236) reactions is found to have no significant variation with energy and to be larger than for the charge exchange reactions. The cross sections for all four reactions show a dip in the forward direction, indicating the importance of spin-flip amplitudes.

Systematic Study of K+- Charge Exchange from 3-GeV/c to 6-GeV/c

Diebold, R. ; Ayres, D.S. ; Greene, A.F. ; et al.
Phys.Rev.Lett. 32 (1974) 904, 1974.
Inspire Record 89016 DOI 10.17182/hepdata.21284

Differential cross sections for K−p→K¯0n and K+n→K0p have been measured at 3, 4, and 6 GeV/c using a data sample of 6000 events. Contrary to simple exchange-degenerate models, the ratio of K+ to K− cross sections was found to be approximately 1.35, with little dependence on either s or t. Both reactions show a shallow dip near the forward direction, suggesting the importance of spin-flip amplitudes.

Phys.Rev.D 9 (1974) 42-48, 1974.
Inspire Record 93128 DOI 10.17182/hepdata.21955

We have studied the reactions K+p→K0Δ++(1236) at 15.7 GeVc, K−p→K¯0n at 10.7 and 15.7 GeVc, and K−p→K¯0Δ0(1236) at 15.7 GeVc in the BNL Double Vee Magnetic Spectrometer. The π+ and π− from the decays of forward K0's were detected and the above reactions were identified by a missing-mass technique. Total and differential cross sections are presented for the first two reactions and a total cross section for the third.
