$K^- p$ total and elastic cross sections at 2.66 GeV/c

Ficenec, J.R. ; Trower, W.P. ;
Phys.Lett.B 25 (1967) 369-372, 1967.
Inspire Record 1389627 DOI 10.17182/hepdata.29435

At an incident kaon momentum of 2.66 GeV/ c we have measured the total and elastic cross sections to be 30.2 and 5.70 mb respectively. The elastic scattering angular distribution is dominated by a single diffraction peak; and when this peak is fit to an exponential in momentum transfer t , the first order term is both necessary and sufficient. This fit evaluated at t =0 is consistent with a purely imaginary forward scattering amplitude. Our data when compared with that of others indicates no shrinkage of the diffraction peak. The entire angular distribution was also fit to a Legendre series, with order 9 being required to represent the data.

Experimental Study of Single Particle Inclusive Hadron Scattering and Associated Multiplicities

Brenner, A.E. ; Carey, David C. ; Elias, J.E. ; et al.
Phys.Rev.D 26 (1982) 1497, 1982.
Inspire Record 169446 DOI 10.17182/hepdata.4112

An experiment using the Fermilab Single Arm Spectrometer (SAS) facility and an associated nonmagnetic vertex detector studied the reactions a+p→c+X, where a and c were π±, K±, p, or p¯. Extensive measurements were made at 100 and 175 GeV/c beam momenta with the outgoing hadrons detected in the SAS covering a kinematic range 0.12<x<1.0 and pT<1.25 GeV/c. Additional data covering a more restricted range in x were also gathered at 70 GeV/c incident momentum. In this high-statistics experiment, the identification of both the incoming and outgoing charged hadrons were made with a total of eight Čerenkov counters. New and extensive single-particle inclusive data for charged-particle production in low-pT hadronic fragmentation are presented. The average associated charged-particle multiplicity and pseudorapidity distributions are also given.

Structures in K- Nucleon Total Cross-Sections Below 1.1-GeV/c

Carroll, A.S. ; Chiang, I.H. ; Kycia, T.F. ; et al.
Phys.Rev.Lett. 37 (1976) 806, 1976.
Inspire Record 112758 DOI 10.17182/hepdata.21041

Total cross sections of K−p and K−d have been measured between 410 and 1070 MeV/c with high statistical precision. In addition to the well known Λ(1520), Λ(1820), and Σ(1769), we confirmed the presence of the Λ(1692) and the Σ(1670). We have also observed several structures which could be Y* resonances: Λ(1646), Λ(1735), Σ(1583), Σ(1608), Σ(1633), and Σ(1715).

Real Part of the K+- p Forward Scattering Amplitude at 4.2-GeV/c, 7-GeV/c and 10-GeV/c

Baillon, P. ; Declais, Y. ; Ferro-Luzzi, M. ; et al.
Nucl.Phys.B 107 (1976) 189-210, 1976.
Inspire Record 108434 DOI 10.17182/hepdata.35862

The differential cross section of K − p and K + p elastic scattering has been measured at 4.2, 7 and 10 GeV/ c in the very forward region of scattering angles. The measurements have been made at the CERN PS by means of multiwire proportional chambers and counters. The region of momentum transfers t is 0.001 ⩽ | t | ⩽ 0.10 GeV 2 at the highest momentum and 0.001 ⩽ | t | ⩽ 0.03 GeV 2 at the lowest. Over these regions the Coulomb and the nuclear amplitudes reach their maximum interference. We have used a parametrisation of the above amplitudes to determine the value of the real part of the nuclear forward scattering amplitude. A dispersion relation fit has then been performed using these and earlier measurements; the asymptotic behaviour of the K ± p real parts has been examined in the light of this fit.

Cross-Sections and Charged Multiplicity Distributions for $\pi^- p$ and $K^- p$ Interactions at 147 GeV/c.

Fong, D. ; Heller, M. ; Shapiro, A.M. ; et al.
Nucl.Phys.B 102 (1976) 386-404, 1976.
Inspire Record 112604 DOI 10.17182/hepdata.36057

The results presented in this paper were obtained from a 105 000 frame exposure of the FNAL Hybrid Proportional Wire Chamber-30 inch Bubble Chamber System, in a tagged beam of 147 GeV/ c negative particles. Elastic, total and topological cross sections were obtained for both π − p and K − p interactions. Comparisons with other data, taken with various beam particles over large momentum intervals, show good agreement with KNO scaling, and similarity in the scaling behavior of σ n for the different beam particles.

An analysis has been made of 64 600 events of the type K−p→K−p and 22 800 events of the type K−p→K¯0n in the Berkeley 25-in. hydrogen bubble chamber. Differential cross sections have been measured in intervals of 10 MeV/c over the momentum range 220 to 470 MeV/c. Legendre-polynomial fits to the distributions have been made, and the coefficients show structure from the resonant D-wave [Λ(1520)] and background S and P waves. No new structure is observed. The total K−p cross section determined from measurements of all final states seen in this exposure is also presented.
