Abstract

The highest-energy measurement of Delta sigma(L)(pp) and the first ever measurement of Delta sigma(L)((p) over bar p), the differences between proton-proton and antiproton-proton total cross sections for pure longitudinal spin states, are described. Data were taken using 200-GeV/c polarized beams incident on a polarized-proton target. The results are measured to be Delta sigma(L)(pp) = -42 +/- 48(stat) +/- 53(syst) mu b and Delta sigma(L)((p) over bar p) = -256 +/- 124(stat) +/- 109(syst) mu b. Many tests of systematic effects were investigated and are described, and a comparison to theoretical predictions is also given. Measurements of parity nonconservation at 200 GeV/c in proton scattering and the first ever of antiproton scattering have also been derived from these data. The values are consistent with zero at the 10(-5) level.
