Liang, Zuo-tangBoros, Csaba Ladislaus Laszlo2006-07-052006-07-051997Physical Review Letters, 1997; 79(19):3608-36110031-9007http://hdl.handle.net/2440/10924It 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 a 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.en©1997 American Physical SocietyJournal article001997221610.1103/PhysRevLett.79.3608
