Asymmetry in Charmed Particles Production in ${\Sigma }^{-}$ beam

Abstract

We present the calculation of the inclusive $x_F$-distributions of charmed hadrons, produced in high-energy ${\Sigma }^{-}$-beam. The 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. We predict the additional asymmetry in the production of charmed hadrons due to the different distributions of the valence s and d quarks in ${\Sigma }^{-}$-beam.
