Abstract
The highest-energy measurement of Delta sigma(L)(pp) and the first eve r measurement of Delta sigma(L)((p) over bar p), the differences betwe en proton-proton and antiproton-proton total cross sections for pure l ongitudinal spin states, are described. Data were taken using 200-GeV/ c polarized beams incident on a polarized-proton target. The results a re measured to be Delta sigma(L)(pp) = -42 +/- 48(stat) +/- 53(syst) m u b and Delta sigma(L)((p) over bar p) = -256 +/- 124(stat) +/- 109(sy st) mu b. Many tests of systematic effects were investigated and are d escribed, and a comparison to theoretical predictions is also given. M easurements of parity nonconservation at 200 GeV/c in proton scatterin g and the first ever of antiproton scattering have also been derived f rom these data. The values are consistent with zero at the 10(-5) leve l.
