Asymmetries Between Strange and Antistrange Particle Production in Pion-Proton Interactions

Recent measurements of the asymmetries between Feynman $x$ distributions of strange and antistrange hadrons in ${\pi }^{-}A$ interactions show a strong effect as a function of $x_F$. We calculate strange hadron production in the context of the intrinsic model and make predictions for particle/antiparticle asymmetries in these interactions.
