Abstract
We have measured the analyzing power in , , and production by a polarized proton beam at 13.3 and 18.5 GeV/c. The data cover the central and the beam fragmentation region, in the transverse-momentum range up to 2 GeV/c. The results indicate that sizable effects are present at high and also persist into the hard-scattering region for and . A zero value of the analyzing power was observed for production.
