Description

The polarization of the Λ hyperon produced in the inclusive reaction p+p→Λ+X is measured at 19 GeV/c with a sample of 4975 Λ's. Nonzero values of the polarization are observed for Λ's with transverse momentum larger than 0.6 GeV/c. Somewhat weaker indications of a nonzero effect are seen for values of the Feynman variable |x| larger than 0.8. The triple-Regge formula with only leading Ksup(*) and Ksup(**) trajectories predicts vanishing polarization and is consistent with data at |x| < 0.8 and small transverse momentum. (author)
