First Measurement of the Real Part of a $p p$ Double Spin Flip Amplitude

Gazzaly, M.M. ; Pauletta, G. ; Tanaka, N. ; et al.
Phys.Rev.Lett. 58 (1987) 1084, 1987.
Inspire Record 247888 DOI 10.17182/hepdata.20181

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.

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.

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.

Elastic scattering of anti-protons on protons at 5 gev/c evidence for a backward peak

Chabaud, V. ; Eide, A. ; Lehmann, P. ; et al.
Phys.Lett.B 38 (1972) 449-451, 1972.
Inspire Record 75820 DOI 10.17182/hepdata.5678

Antiproton-proton elastic scattering has been measured at 5 GeV/c. A total of 30 000 events were observed in the angular range 17° < θ cm < 136°, corresponding to 0.3 < − t < 7.7 (GeV/ c 2 ). In addition to the known dip at − t = 0.5 ( GeV / c ) 2 , we observe a structure at about − t = 2 (GeV/ c ) 2 and a backward peak with a slope4.1 ± 0.6 (GeV/ c ) 2 . The extrapolated differential cross-section at u = 0 is 1.3 ± 0.8 μ b/(GeV/ c ) 2 .

Upper limits on rare two-body processes in k- p and anti-p p scattering at high energies

Birnbaum, D. ; Edelstein, R.M. ; Hien, N.C. ; et al.
Phys.Lett.B 31 (1970) 36-39, 1970.
Inspire Record 63230 DOI 10.17182/hepdata.6079

A missing mass spectrometer search was made for several two-body, double charge exchange reactions, including backward K −p and p̄p elastic scattering at 8 and 16 GeV/ c and small momentum transfer. No examples of any of these processes were observed.

STRUCTURE OBSERVED IN THE SPIN SPIN CORRELATION PARAMETER C(LL) = (L, L, 0, 0) IN P P ELASTIC SCATTERING AROUND THETA (C.M.) = 90-DEGREES IN THE REGION P(LAB) = 2.5-GEV/C - 5.0-GEV/C

The spin-spin correlation parameter CLL=(L, L; 0, 0) has been measured for p−p elastic scattering around θc.m.=90° up to plab=5 GeV/c. An interesting energy dependence is observed in CLL and the results are interpreted by comparison with other available data.

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

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.

Simultaneous Measurement of the Spin Parameters p and c(n n) in p p Elastic Scattering at 2, 3, 4, and 6-GeV/c

Miller, D. ; Wilson, C. ; Giese, R. ; et al.
Phys.Rev.D 16 (1977) 2016-2026, 1977.
Inspire Record 126510 DOI 10.17182/hepdata.24496

Using the polarized-beam facility at Argonne National Laboratory and a polarized proton target, simultaneous measurements of the spin parameter P and the spin correlation term CNN were made. Data were obtained and analyzed at beam momenta of 2, 3, 4, and 6 GeV/c in the momentum-transfer-squared interval 0.1≤|t|≤2.8 (GeV/c)2. A preliminary phase-shift analysis of the 2- and 3-GeV/c data is discussed and a comparison with predictions of a particular Regge-pole model at all four energies is made.

We have measured the spin-spin correlation parameter CNN at 2, 3, 4, and 6 GeV/c over the |t| range of 0.1 to 2.0 (GeV/c)2 and have observed a striking energy and |t| dependence in CNN. Polarization data were simultaneously collected and are compared to previous results.
