Large samples of Λ , Σ (1385) and Ξ (1321) hyperons produced in the deep-inelastic muon scattering off a 6 LiD target were collected with the COMPASS experimental setup at CERN. The relative yields of Σ (1385) + , Σ (1385) − , , , Ξ (1321) − , and hyperons decaying into were measured. The ratios of heavy-hyperon to Λ and heavy-antihyperon to were found to be in the range 3.8 % to 5.6 % with a relative uncertainty of about 10 %. They were used to tune the parameters relevant for strange particle production of the LEPTO Monte Carlo generator.
