Abstract

The hadroproduction of D_s mesons is discussed within the framework of the modified Quark-Gluon String model (QGSM) taking into account the decays of corresponding S--wave resonances. A description of the existing experimental data on inclusive spectra of D_s - mesons production in πp - collision and asymmetry of leading (D_s^-) and nonleading (D_s⁺) mesons in Σ^- p-- interaction is obtained. The predictions for cross sections and leading/nonleading asymmetry in πp - and Σ^- p-- collision for different initial momenta are also given.
