Abstract
The analyzing power, A(N), in inclusive charged-pion production has been me asured using a similar to 22-GeV/c transversely polarized proton beam on a carbon target. A large A(N) was found for x(F) > 0.5 and for 0.6 < p(T) < 1 .2 GeV/c, with similar magnitudes and opposite sign for pi(+) and pi(-). Th is mirror behavior and the magnitudes are similar to pi(+/-) production fro m 200-GeV/c polarized protons on a hydrogen target. The analyzing power for inclusive proton production has also been measured and is consistent with zero. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
