Abstract

We have measured the polarization of $\Xi^-$ hyperons produced inclusively by a $\Sigma^-$ beam of 340 GeV/c momentum in nuclear targets. From a sample of 880000 identified $\Xi^-$ decays, polarizations were determined in the range 0 < x F < 0.9 and $p_t\leq1.6$ GeV/c. The polarization w.r.t. the production normal is negative for $x_F \geq $ 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 .
