摘要：

In the framework of Quark-Gluon-String Model developed recently in ITEP we calculate spectra of charmed particles D, D-s,Lambda(c),Xi(c),Omega(c) in hadron-hadron collisions taking into account the decays of S-wave resonances like D*,D*(s), Sigma(c),Sigma*(c),Xi*(c),Xi'(c), and Omega*(c). We describe the bulk of the existing data on D, D*, ad Lambda(c) production in pi p and pp collisions and predict the yield of charmed particles in Sigma(-)p and Xi(-)p reactions at hyperon beam energies of 340 GeV/c and 600 GeV/c. Because of significant production of baryon resonances our predictions for unfavored fragmentation differ from predictions of other models which do not take resonance production into account.
