Measurement of the polarization parameter in backward pi+ p elastic scattering at 1.60, 1.80, 2.11, and 2.31 gev/c

Burleson, G. ; Hill, D. ; Kato, S. ; et al.
Phys.Rev.Lett. 26 (1971) 338-340, 1971.
Inspire Record 69051 DOI 10.17182/hepdata.21558

Measurements of polarization in π+p elastic scattering have been made at 1.60, 1.80, 2.11, and 2.31 GeVc. The data cover the entire angular range, with emphasis on the backward region. Comparisons have been made with both u-channel and t-channel models, as well as with predictions of phase-shift analyses. While the agreement is generally poor in all cases, the best agreement is with some t-channel predictions.

Measurements of polarization in pi- p elastic scattering at large angles

Hill, D. ; Koehler, P.F.M. ; Novey, T.B. ; et al.
Phys.Rev.Lett. 27 (1971) 1241-1243, 1971.
Inspire Record 68894 DOI 10.17182/hepdata.229

We have made measurements of polarization in π−p elastic scattering, with emphasis over the backward region, at 1.60 to 2.28 GeVc. The results indicate the absence of u-channel dominance in the backward region, as was observed in the case of π+p scattering. Comparisons have been made with predictions of various phase-shift analyses which show that the agreement is generally very poor in the backward region.

Polarization in π−p elastic scattering, with emphasis in the region around the secondary dip and also θc.m.=90°, has been measured at 2.93 and 3.25 GeV/c. We observe an interesting sign change in this angular region.

Measurement of the polarization parameter in k+ p elastic scattering

Barnett, B.A. ; Laasanen, A.T. ; Koehler, P.F.M. ; et al.
Phys.Rev.D 8 (1973) 2751-2764, 1973.
Inspire Record 93326 DOI 10.17182/hepdata.22081

Full angular distributions of the polarization parameter in elastic K+p scattering at 1.37, 1.45, 1.60, 1.71, 1.80, 1.89, 2.11, and 2.31 GeV/c are presented. These data were obtained in an experiment at the Zero Gradient Synchrotron using a polarized proton target with arrays of scintillation and Čerenkov counters to detect the scattered particles.

Energy Dependence of the Spin Spin Correlation Parameter C(ll) = (L, L : O, O) in $p p$ Elastic Scattering Around $\theta$ (Center-of-mass) = 90-degrees

Auer, I.P. ; Beretvas, A. ; Colton, E. ; et al.
Phys.Rev.Lett. 41 (1978) 1436, 1978.
Inspire Record 131077 DOI 10.17182/hepdata.20865

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.

The spin-spin correlation parameter CSS=(S,S;0,0) has been measured for p−p elastic scattering over a large angular range. The data are particularly useful in checking currently available phase-shift solutions.

Measurements of Spin Spin Correlation Parameters Up to 2.5-{GeV}/$c$ Incident Momentum for a Decisive Clarification of the Structure Observed in the $p p$ System

Auer, I.P. ; Colton, E. ; Ditzler, W.R. ; et al.
Phys.Rev.Lett. 51 (1983) 1411, 1983.
Inspire Record 191101 DOI 10.17182/hepdata.20512

Recent data are presented on spin-spin correlation parameters CLL=(L,L;0,0) and CSL=(S,L;0,0) at forward angles from 1.18 to 2.47 GeV/c incident momenta in proton-proton elastic scattering. Values for ΔσL (inelastic) are derived and are shown to disagree with predictions of theoretical models attempting to describe p−p scattering without dibaryon resonances. Finally, the CLL and CSL data discriminate among various phase-shift solutions, and will lead to a clarification of the p−p phase shifts.

MEASUREMENT OF THE P P ELASTIC SCATTERING SPIN PARAMETER C(LL) AT 11.75-GEV/C FOR THETA (C.M.) = 48-DEGREES - 90-DEGREES

Auer, I.P. ; Colton, E. ; Ditzler, W.R. ; et al.
Phys.Rev.Lett. 52 (1984) 808-810, 1984.
Inspire Record 202204 DOI 10.17182/hepdata.20434

Results are presented of a measurement of the proton-proton elastic-scattering spin parameter CLL=(L,L;0,0) at 11.75 GeV/c and θc.m.=48°−90°. The value of CLL is nearly constant and is approximately -0.16 in this angular region. This behavior is consistent with only one of the many models proposed describing the interaction via the hard scattering of two quarks.
