Polarization in p p Elastic Scattering at Large Four Momentum Transfers

Bryant, G.W. ; Corcoran, M. ; Crittenden, R.R ; et al.
Phys.Rev.D 13 (1976) 1-4, 1976.
Inspire Record 113034 DOI 10.17182/hepdata.24788

New results are presented from the continuation of an experiment designed to study the polarization in elastic p−p scattering at large four-momentum transfers. A high-intensity unpolarized proton beam of momentum 12.3 GeV/c was incident on a propanediol polarized proton target and both final-state protons were detected and momentum-analyzed in multiwire proportional chamber spectrometers. The measurements spanned the t range 1.5<|t|<6.2 (GeV/c)2. The results are discussed in the framework of optical, exchange, and parton models.

Simultaneous Measurement of 2 and 3 Spins in Proton Proton Elastic Scattering at 6-GeV/c

Fernow, Richard C. ; Gray, S.W. ; Krisch, A.D. ; et al.

The elastic cross section for proton proton scattering at 6 GeV c was measured using a 70% polarized beam and a 75% polarized target at the Argonne ZGS. In the range P ⊥ 2 = 0.5 → 2.0( GeV c ) 2 we obtained small error measurements for the ↑↑, ↓↓ and ↑↓ initial spin states perpendicular to the scattering plane. At P ⊥ 2 = 0.5 we also measured the recoil spin and found that the 5 different cross sections were very unequal.

Measurement of elastic proton proton scattering in pure initial-spin states

O' Fallon, J.R. ; Parker, E.F. ; Ratner, L.G. ; et al.
Phys.Rev.Lett. 32 (1974) 77-79, 1974.
Inspire Record 94699 DOI 10.17182/hepdata.21307

An experiment was done using an accelerated polarized proton beam and a polarized proton target. The elastic cross section for proton-proton scattering at 6.0 GeV/c and P⊥2=0.5−1.6 (GeV/c)2 was measured in the spin states ↑ ↑, ↓ ↓, and ↑ ↓ perpendicular to the scattering plane. The cross sections were found to be unequal by up to a factor of 2.

Measurement of the Depolarization Parameter in Elastic Proton Proton Scattering at 3 and 6-GeV/c

Abshire, G.W. ; Bryant, G.W. ; Corcoran, M. ; et al.
Phys.Rev.D 12 (1975) 3393-3398, 1975.
Inspire Record 104822 DOI 10.17182/hepdata.24809

Results are presented from an experiment designed to make the first systematic study of the depolarization parameter in elastic proton-proton scattering at high energies. Measurements were made at 3.0 and 6.0 GeV/c at |t| values extending to 1.7 (GeV/c)2 at the higher momentum. A high-intensity unpolarized proton beam was incident on a polarized proton target and the polarization of the elastically scattered recoil protons was determined with a carbon analyzer. The results are discussed in the framework of optical and exchange models.
