Optimization of LEPTO/JETSET generator parameters for deep inelastic scattering of charged leptons

Results of measurements of heavy hyperon and antihyperon yields in deep inelastic muon scattering obtained in the COMPASS experiment and their matching with Monte Carlo predictions are presented. Those of relative yields of heavy hyperons Σ(1385)+, Σ(1385)−, \(\bar \Sigma (1385)^ -\), \(\bar \Sigma (1385)^ +\), Ξ(1321)−, \(\bar \Xi (1321)^ +\) with respect to Λ and \(\bar \Lambda\) baryons were used to optimize the LEPTO/JETSET generator, which is heavily exploited for event simulation in a deep inelastic scattering region.
