Single-Spin Asymmetries in Inclusive Charged Pion Production by Transversely Polarized Antiprotons. Academic Article uri icon

abstract

  • The analyzing power AN in inclusive and + production has been measured with a 200 GeV/c transversely polarized antiproton beam over a wide xF range (0.2 xF 0.9) and at moderate pT(0.2 pT 1.5GeV/c). The asymmetry AN increases with increasing xF from zero to large positive values for S, and decreases from zero to large negative values for +S. A threshold for the onset of the asymmetry is observed about pT 0.5 GeV/C, below which AN is essentially zero and above which AN ncreases (decreases) with pT for S (+S) in the covered pT range. 1996 The American Physical Society.
