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.

K- p elastic scattering at 10-GeV/c

The Aachen-Berlin-CERN-London-Vienna collaboration Bartsch, J. ; Deutschmann, M. ; Kraus, G. ; et al.
Nucl.Phys.B 29 (1971) 398-404, 1971.
Inspire Record 68635 DOI 10.17182/hepdata.33567

Results are presented on elastic scattering of 10.1 GeV/ c K − mesons on protons, based on a sample of 16 261 kinematically-fitted bubble-chamber events. The differential cross section is given over the | t |- range of 0.06 to 2.5 GeV 2 and is fitted with the expressions a e bt , A e Bt + Ct 2 and ( P e Qt + Re St ) over various intervals of t . The results are compared with those of other experiments at nearby energies. Upper limits of | α | < 0.28 and σ B < 0.4 μ b (both at a 90% confidence level) are given for the ratio of real to imaginary part of the forward-scattering amplitude and the backward-elastic-scattering cross section, respectively.

ERROR INCLUDES STATISTICAL ERROR AND ERROR IN TOTAL CROSS SECTION USED FOR NORMALIZATION. EXTRAPOLATION OF D(SIG)/DT TO T=0 PROVIDES ABOUT 0.5 PCT UNCERTAINTY.
