Abstract

We have measured the polarization of Ξ− hyperons produced inclusively by a Σ− beam of 340 GeV/c momentum in nuclear targets. From a sample of 880000 identified Ξ− decays, polarizations were determined in the range 0 < x F < 0.9 and pt≤1.6 GeV/c. The polarization w.r.t. the production normal is negative for xF≥ 0.3. At fixed values of x F , its magnitude increases with p t to maximum values which reach about 20% at large x F .
