Single-spin asymmetries in inclusive charged pion production by transversely polarized antiprotons.

The analyzing power AN in inclusive π− and π+ 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 π−'s, and decreases from zero to large negative values for π+'s. A threshold for the onset of the asymmetry is observed about pT∼0.5GeV/c, below which AN is essentially zero and above which AN increases (decreases) with pT for π−'s ( π+'s) in the covered pT range.

The Reaction $\pi^- p \to K^0 \Lambda^0$ Up to 2375-{MeV}/$c$: New Results and Analysis

Saxon, D.H. ; Baker, R.D. ; Bell, Kenneth Watson ; et al.
Nucl.Phys.B 162 (1980) 522-546, 1980.
Inspire Record 142072 DOI 10.17182/hepdata.34549

New data are presented on the reaction π − p→K 0 Λ 0 at 13 incident momenta between 1395 and 2375 MeV/ c . A partial-wave analysis has been performed using these data and previous data at lower momenta. The resulting resonance parameters are in broad agreement with recent πN analyses and with the predictions of SU(6) W × O(3) for the couplings.

Differential cross-section and polarization measurements for the reaction π − p → K 0 Σ 0 are presented from 1395 to 2375 MeV/ c incident beam momentum. The polarization data from an earlier experiment, from thershold to 1334 MeV/ c , have been re-analysed by an improved method leading to a substantial reduction in the errors.

Large $\chi_F$ Spin Asymmetry in $\pi^0$ Production by 200 GeV Polarized Protons

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<pT<2 GeV/c. AtxF>0.3, the asymmetry rises with increasingxF and reaches a value ofAN=0.15±0.03 in the region 0.6<xF<0.8. This result provides new input regarding the question of the internal spin structure of transversely-polarized protons.

A description is given of the experimental techniques and investigation results of the parameters Σ , T , P for the γ p→p π 0 reaction using linear polarized photons and a polarized proton target. The measurements have been made in the photon energy range 280–450 MeV at pion c.m. angles between 60° and 135°. The new experimental data are used in an energy-independent channel multipole analysis without the Watson theorem.
