We present results for the hypercharge exchange reaction K − p→f' λ from a high statistics experiment at 8.25 GeV/ c using the CERN 2m HBC. The total and differential cross sections have been measured; the polarisation of the Λ hyperon and the f' density matrix elements have been calculated as functions of momentum transfer. We also present detailed information on the relative strength of the natural and unnatural parity exchange contributions to the production mechanism.

Proton Polarization in $p p$ Elastic and Inclusive Processes at Beam Momenta From 20-{GeV}/$c$ to 400-{GeV}/$c$

Corcoran, M. ; Ems, S.C. ; Gray, S.W. ; et al.
Phys.Rev.D 22 (1980) 2624, 1980.
Inspire Record 9773 DOI 10.17182/hepdata.4324

The polarization of the recoil proton has been measured in both high-energy elastic and inclusive proton-proton scattering at the internal-target area of Fermi National Accelerator Laboratory. The polarization in elastic scattering was measured at a number of center-of-mass energies up to s=19.7 GeV. Indications of negative polarization were seen at the higher center-of-mass energies for t values of -0.6, -0.8, and -1.0 (GeV/c)2. In the inclusive process p+p→p↑+X the polarization was found to be independent of beam energy from 100 to 400 GeV for xF values of -0.7, -0.8, -0.9. The polarization at PT=1.0 GeV/c, xF=−0.7 and xF=−0.8 was less than 2.5%. This is significantly lower than the corresponding measurements reported for Λ0 inclusive polarization.

The results of an experiment conducted at Fermilab to measure the polarization of the final-state proton in the reaction p+p→p↑+X and p+C→p↑+X are presented. Measurements were made at beam energies of 100, 200, 300, and 400 GeV for PT from 0.5 to 1.5 GeV/c and xF between - 0.7 and - 0.9.

Proton Proton Elastic Scattering from 150-MeV to 515-MeV

Inspire Record 123232 DOI 10.17182/hepdata.38563

The parameters D, R, R' and P for pp elastic scattering have been measured in the centre-of-mass angular range 13 degrees to 58 degrees with an accuracy of about +or-0.02 at 209, 324, 379, 425 and 515 MeV. These results are incorporated with earlier data into a phase-shift analysis. Phase-shifts are generally in agreement with the theoretical predictions of the Paris group, although the F-wave spin-orbit combination is rather stronger than predicted. The fitted value for the pi 0pp coupling constant in g02=14.06+or-0.65.
