The Acceleration of Polarized Protons to 22-{GeV}/$c$ and the Measurement of Spin Spin Effects in $p$ (Polarized) + $p$ (Polarized) $\to p + p$

Accelerating polarized protons to 22 GeV/c at the Brookhaven Alternating Gradient Synchro- tron required both extensive hardware modifications and a difficult commissioning process. We had to overcome 45 strong depolarizing resonances to maintain polarization up to 22 GeV/c in this strong-focusing synchrotron. At 18.5 GeV/c we measured the analyzing power A and the spin-spin correlation parameter Ann in large- P⊥2 proton-proton elastic scattering, using the polarized proton beam and a polarized proton target. We also obtained a high-precision measurement of A at P⊥2=0.3 (GeV/c)2 at 13.3 GeV/c. At 18.5 GeV/c we found that Ann=(-2±16)% at P⊥2=4.7 (GeV/c)2, where it was about 60% near 12 GeV at the Argonne Zero Gradient Synchrotron. This sharp change suggests that spin-spin forces may have a strong and unexpected energy dependence at high P⊥2.

Asymmetry measurements for elastic scattering of k+ mesons by polarized protons

Ehrlich, R.D. ; Etkin, A. ; Glodis, P. ; et al.
Phys.Rev.Lett. 26 (1971) 925-928, 1971.
Inspire Record 69016 DOI 10.17182/hepdata.21466

We report measured values of the asymmetry in the elastic scattering of K+ mesons from polarized protons. The data were obtained at fourteen incident K+ momenta from 1.33 to 2.58 GeVc; the approximate angular range covered was −0.85<cosθKc.m.<0.9. We compare our results with other available measurements and note several significant differences.

Measurements of the Polarization Parameter in $K^+ P$ Elastic Scattering at Low-energies

Lovett, B.R. ; Hughes, V.W. ; Mishina, M. ; et al.
Phys.Rev.D 23 (1981) 1924-1932, 1981.
Inspire Record 170184 DOI 10.17182/hepdata.24149

Results of measurements of the polarization parameter in K+p elastic scattering at 650, 700, 845, and 940 MeV/c are presented. Details of the measurements are described and results are compared with previous measurements and partial-wave parametrizations of the data. The implication of the existence of Z* resonances in light of these results is discussed.
