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.

Proton proton triple scattering at 1.9 gev

Phys.Rev. 179 (1969) 1304-1314, 1969.
Inspire Record 55504 DOI 10.17182/hepdata.5476

We have measured the Wolfenstein triple-scattering parameters R, D, and A′ at 1.9 GeV for p−p scattering at 90° in the c.m. system. We find that R=0.11±0.16, A′=−0.54±0.16, and D=0.91±0.21, where these parameters are defined in the c.m. system. The possibility of a vector character for the strong inter-actions is discussed. We conclude that neither a single vector-meson exchange nor a single pseudoscalar-meson exchange can account for the data. Spin effects are found to remain an important part of the nucleon-nucleon interaction at four-momentum transfer −t=1.8 (GeV/c)2.

Inspire Record 98421 DOI 10.17182/hepdata.32031

Differential cross sections for elastic scattering of negative kaons on protons are presented for 13 incident laboratory momenta between 1094 MeV/c and 1377 MeV/c. The data show the characteristic forward diffraction-like peak and backward dip and are adequately described in shape by certain published partial-wave analyses of the N system.

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

J.Phys.G 4 (1978) 1025, 1978.
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.

Pi-minus p elastic scattering at 2.51, 2.76, and 3.01 gev/c near t approximately equals -3 (gev/c)-squared

Phys.Rev.Lett. 23 (1969) 600-602, 1969.
Inspire Record 58788 DOI 10.17182/hepdata.21636

Differential cross sections for the elastic scattering of negative pions from hydrogen have been measured over a limited range of squared four-momentum transfer (t) in the vicinity of t≃−3 (GeV/c)2 for incident pion momenta of 2.51, 2.76, and 3.01 GeV/c. These measurements confirm the existence of a minimum in the differential cross section in this region of incident momentum and scattering angle. The minimum occurs at a smaller value of t [t≃−2.6 (GeV/c)2] than has been observed at higher momenta.

Inspire Record 194351 DOI 10.17182/hepdata.30742

Differential cross sections for π + p elastic scattering were measured for seven incident energies from 65 to 140 MeV at laboratory scattering angles between 93° and 165°. The results are compared with previous results of Bertin et al. and the phase-shift analysis of Arndt and Roper. Agreement between the phase-shift analysis and the data is good.

Measurements of pi- p elastic scattering from 1.71 to 5.53 gev/c

Fellinger, M. ; Gutman, E. ; Lamb, R.C. ; et al.
Phys.Rev.D 2 (1970) 1777-1782, 1970.
Inspire Record 61322 DOI 10.17182/hepdata.47092

The π−p elastic scattering differential cross section has been obtained at 18 incident momenta from 1.71 to 5.53 GeV/c. The measurements were taken over a limited range of squared four-momentum transfer t near the forward direction. The statistical accuracy and resolution of these data are comparable to, or better than, existing data. The parameter b in the expression dσdt=Aebt has been determined at each of our incident momenta, and a large (∼25%) enhancement in b as a function of momentum is observed at a c.m. energy of ∼2290 MeV. The relation of this bump in b with the well-established bump in the total π−p cross section at ∼2200 MeV is discussed.
