Abstract

The analyzing power in inclusive charged pion production has been measured using the 200 GeV Fermilab polarized proton beam. A striking dependence in x_F is observed in which A_N increases from 0 to 0.42 with increasing x_F for the π⁺ data and decreases from 0 to -0.38 with increasing x_F for π^- data. The kinematic range covered is 0.2≤x_F≤0.9 and 0.2≤p_T≤2.0 GeV/c. In a simple model our data indicate that at large x_F the transverse spin of the proton is correlated with that of its quark constituents.
