The asymmetry ANN for pp elastic scattering has been measured at 800 and 650 MeV in the region of Coulomb-nuclear interference. The data have been analyzed to extract the real part of a spin-spin scattering amplitude. Results are compared with the predictions of forward dispersion relations. They disagree significantly at 650 MeV.

Aprile, E. ; Eisenegger, C. ; Hausammann, R. ; et al.

Phys.Rev.Lett. 46 (1981) 1047-1050, 1981.

Inspire Record 169865 DOI 10.17182/hepdata.20658

We have made, for the first time, a direct reconstruction of the pp elastic-scattering matrix at 579 MeV from a series of experiments performed at the Schweizerisches Institut für Nuklearforschung polarized-beam line. Fifteen observables consisting of the polarization, two-spin correlation and transfer parameters, and three-spin parameters were measured at seven angles between 66° and 90° (c. m.). The experimental results and reconstructed amplitudes are presented and compared to phase shift analysis.

We have measured the spin-spin correlation parameter CLL=(L, L;0, 0) in p−p elastic scattering around θc.m.=90° from plab=1.0 to 3.0 GeV/c. We observe a rapid energy dependence in CLL and describe our interpretation of the results.

Measurement of the Spin Spin Correlation Parameter C(SS) in p p Elastic Scattering at 6-GeV/c

Auer, I.P. ; Hill, D. ; Miller, R.C. ; et al.

Phys.Rev.Lett. 37 (1976) 1727, 1976.

Inspire Record 4268 DOI 10.17182/hepdata.21043

We have made the first measurement of the spin-spin correlation parameter CSS in pp elastic scattering at 6 GeV/c over the |t| range from 0.05 to 1.5 (GeV/c)2. The measured CSS data points are all negative, and their absolute values increase with |t|. The results are compared with some existing attempts to describe the pp scattering process.

Measurements of the Spin Rotation Parameter R in p p and pi+ p Elastic Scattering at 45-GeV/c

Inspire Record 113035 DOI 10.17182/hepdata.27706

The spin rotation sf R in pp and π + p elastic scattering at 45 GeV/c has been measured at the Seppukhov accelarator, for z . sfnc ; t |; ranging from 0.2 to 0.5 (GeV/) 2 . The results are presented, together with previous R measurements at lower energies. The equality of the values for R in proton-proton and pion-proton scattering, within the experimental errors, is a test of factorization of the residues in the pomeron exchange.

Polarization Measurements in π p+ p and K p+ p elastic scattering at 6 and 12 GeV/ c with the CERN polarized deuteron target

Nucl.Phys.B 151 (1979) 206-212, 1979.

Inspire Record 145595 DOI 10.17182/hepdata.34795

The polarization in π + p → π + p and K + p → K + p has been measured at 6 and 12 GeV/ c in the four-momentum transfer interval 0.1 ⩽ | t | ⩽ 2.0 (GeV/ c ) 2 by scattering on protons of a polarized deuteron target. Comparison with existing results obtained with polarized proton targets shows good general agreement and no evidence for asymmetry effects due to the presence of the spectator neutron. For K + p elastic scattering polarization the experiment yields improved statistics, especially at 6 GeV/ c

MEASUREMENT OF THE TOTAL CROSS-SECTION DIFFERENCE DELTA (SIGMA-L) (P P IN THE ENERGY RANGE FROM 0.52-GEV TO 2.8-GEV

Bystricky, J. ; Chaumette, P. ; Deregel, J. ; et al.

Phys.Lett.B 142 (1984) 130-134, 1984.

Inspire Record 206656 DOI 10.17182/hepdata.30540

The total cross section difference Δα L (pp) for proton-proton scattering with beam and target polarized longitudinally parallel and antiparallel, respectively, has been measured using the polarized proton beam from SATURNE II and a frozen spin polarized proton target. The beam polarization was reversed from pulse to pulse, and at each energy Δα L was measured for both signs of target polarization. The data below 800 MeV confirm the previously observed structures. The cross section difference is found to change by 8.0 ± 0.5 mb between 520 MeV and 760 MeV. At the higher energies the results show no indication for similar structures or for a change of the sign of Δα L .
