TL;DR: In this article, the single-spin asymmetry of antiprotons on protons was measured at Fermilab over a wide range of x{sub F, and it was observed that A{sub N}(anti pp) has the same sign, a similar x-sub F dependence, and about half the magnitude as A {pi}{sup 0} production by protons.

TL;DR: The analyzing power A(N) in inclusive pi(-) and pi(+) production has been measured with a 200 GeV/c transversely polarized antiproton beam over a wide x(f) range and the asymmetry increases with increasing x(F) from zero to large positive values for pi(-,)s, and decreases fromzero to large negative values forpi(+,)s.
