摘要：

We report on the first measurement of the single spin analyzing power (A(N)) at root s = 200 GeV, obtained by the pp2pp experiment using polarized proton beams at the Relativistic Heavy Ion Collider (RHIC). Data points were measured in the four momentum transfer t range 0.01 <= vertical bar t vertical bar <= 0.03(GeV/c)(2). Our result, averaged over the whole vertical bar t vertical bar-interval is about one standard deviation above the calculation, which uses interference between electromagnetic spin-flip amplitude and hadronic non-flip amplitude, the source of A(N). The difference could be explained by an additional contribution of a hadronic spin-flip amplitude to A(N).
