Charmed hadrons production in high-energy ${\mathrm{\Sigma }}^{-}$ beam

We present the calculation of the inclusive x_F-distributions of charmed hadrons, produced in high-energy ${\mathrm{\Sigma }}^{-}$-beam. Our calculation is based on the modified mechanism of charmed quarks fragmentation as well as on the mechanism of c-quark recombination with the valence quarks from initial hadrons.
