Single-spin asymmetries and invariant cross sections of the high transverse-momentum inclusive pi0 production in 200 GeV/c proton-proton and antiproton-proton interactions

The ?0 inclusive and semi-inclusive, single-spin asymmetries have been measured using transversely-polarized, 200-GeV/c proton and antiproton beams colliding with an unpolarized hydrogen target. The measured asymmetries are consistent with a value of zero within the error bars for the kinematic regions, -0.15
