Hyperon polarization and single spin left-right asymmetry in inclusive production processes at high-energies
Aug, 1997Citations per year
Abstract:
It is shown that the polarization of hyperons observed in high energy collisions using unpolarized hadron beams and unpolarized nucleon or nuclear targets is closely related to the left-right asymmetries observed in single spin inclusive hadron production processes. The relationship is most obvious for the production of the hyperons which have only one common valence quark with the projectile. Examples of this kind are given. Further implications of the existence of large polarization for hyperon which has two valence quarks in common with the projectile and their consequences are discussed. A comparison with the available data is made. Further tests are suggested.- hadron nucleon: inclusive reaction
- hadron nucleus: nuclear reaction
- p: polarized beam
- hyperon: hadroproduction
- hyperon: polarization
- polarization: asymmetry
- numerical calculations: interpretation of experiments
