Single-spin asymmetries for hadrons have been measured in collisions of transversely-polarized 40 GeV/c proton beam with an unpolarized liquid hydrogen target. The asymmetries were measured for pi+-, K+-, protons and antiprotons, produced in the central region (0.02 < Xf < 0.10 and 0.7 < Pt < 3.4 GeV/c). Asymmetries for pi+-, K+- and antiprotons show within measurement errors the linear dependence on Xt and change a sign near 0.37. For protons negative asymmetry, independent of Xt has been found. The results are compared with those of other experiments and SU(6) model predictions.

Single Spin Asymmetry in Inclusive Reactions Polarized $P$, $P$ Goes to $\pi^+$, $\pi^-$, and $P$ at High $P$(t) at 13.3-{GeV}/$c$ and 18.5-{GeV}/$c$

Data are presented for the left-right asymmetry in inclusive production of π+, π−, and p with proton beams (polarized normal to the scattering plane) of 13.3 and 18.5 GeV/c incident on a LH2 target. At both energies the asymmetry in π+ production grows steadily to about 25% near the kinematic limit, whereas the π− and p asymmetries are consistent with zero over the measured range of pt, 1.1–2.2 GeV/c.

Proton Polarization in $p p$ Elastic and Inclusive Processes at Beam Momenta From 20-{GeV}/$c$ to 400-{GeV}/$c$

The polarization of the recoil proton has been measured in both high-energy elastic and inclusive proton-proton scattering at the internal-target area of Fermi National Accelerator Laboratory. The polarization in elastic scattering was measured at a number of center-of-mass energies up to s=19.7 GeV. Indications of negative polarization were seen at the higher center-of-mass energies for t values of -0.6, -0.8, and -1.0 (GeV/c)2. In the inclusive process p+p→p↑+X the polarization was found to be independent of beam energy from 100 to 400 GeV for xF values of -0.7, -0.8, -0.9. The polarization at PT=1.0 GeV/c, xF=−0.7 and xF=−0.8 was less than 2.5%. This is significantly lower than the corresponding measurements reported for Λ0 inclusive polarization.

The results of an experiment conducted at Fermilab to measure the polarization of the final-state proton in the reaction p+p→p↑+X and p+C→p↑+X are presented. Measurements were made at beam energies of 100, 200, 300, and 400 GeV for PT from 0.5 to 1.5 GeV/c and xF between - 0.7 and - 0.9.
