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 $\Sigma(1385)^+$, $\Sigma(1385)^-$, $\bar{\Sigma}(1385)^-$, $\bar{\Sigma}(1385)^+$, $\Xi(1321)^-$, and $\bar{\Xi}(1321)^+$ hyperons decaying into \Lambda$($\bar{\Lambda}$)$\pi$ were measured. The ratios of $\Sigma^\pm/\Lambda$, $\bar{\Sigma}^\pm/\bar{\Lambda}$,
$\Xi^{-}/\Lambda$ and $\bar{\Xi}^{+}/\bar{\Lambda}$ were determined.
The measured yields were used to tune the parameters of the LEPTO generator simulating the DIS events.
