The analyzing power, AN, in inclusive charged-pion production has been measured using a ∼ 22-GeV/c transversely-polarized proton beam on a carbon target. A large AN was found for xF > 0.5 and for 0.6 <PT 1.2 GeV/c, with similar magnitudes and opposite sign for π+ and π-. This mirror behavior and the magnitudes are similar to π± production from 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.
