Description: Using data from Fermilab fixed-target experiment E791, we have measured particle-antiparticle production asymmetries for <math>\Lambda^0\!\,</math>, <math>\Xi^-\!\,</math>, and <math>\Omega^-\!\,</math> hyperons in <math>\pi^-\!\,</math> - nucleon interactions at 500 <math>{\rm GeV}/c\!\,</math>. The asymmetries are measured as functions of Feynman-x (<math>x_F\!\,</math>) and <math>p^2_T</math> over the ranges <math>-0.12\leq x_F \leq 0.12</math> and <math>0\leq p^2_T \leq 4 ({\rm GeV}/c)^2</math>. We find substantial asymmetries, even at <math>x_F=0\!\,</math>. We also observe leading-particle-type asymmetries which qualitatively agree with theoretical predictions.
