Large-xF spin asymmetry inπ0 production by 200-GeV polarized protons

1992

The spin asymmetryAN for inclusive π0 production by 200-GeV transversely-polarized protons on a liquid hydrogen target has been measured at Fermilab over a wide range ofxF, with 0.5 0.3, the asymmetry rises with increasingxF and reaches a value ofAN=0.15±0.03 in the region 0.6spin structure of transversely-polarized protons.
