Description

The yields of heavy hyperons and antihyperons have been studied in deep inelastic scattering at the COMPASS experiment at CERN. The relative yields of $\mathrm{\Sigma }(1385{)}^{+}$, $\mathrm{\Sigma }(1385{)}^{-}$, $\overline{\mathrm{\Sigma }}(1385{)}^{-}$, $\overline{\mathrm{\Sigma }}(1385{)}^{+}$, $\mathrm{\Xi }(1321{)}^{-}$, and $\overline{\mathrm{\Xi }}(1321{)}^{+}$ hyperons decaying into \Lambda$($\bar{\Lambda}$)$\pi$weremeasured.Theratiosof$\Sigma^\pm/\Lambda$,$\bar{\Sigma}^\pm/\bar{\Lambda}$,$\Xi^{-}/\Lambda$and$\bar{\Xi}^{+}/\bar{\Lambda}$ were determined. The measured yields were used to tune the parameters of the LEPTO generator simulating the DIS events.
