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 p_t ≤ 1.6 GeV/c. The polarization w.r.t. the production normal is negative for x_F ≥ 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.
