ABSTRACT The structure functions and longitudinal spin asymmetries in semi-inclusive reactions νμ(ν‾μ)N → νμ(ν‾μ)h±X are investigated within the framework of the Standard Model. Expressions for the non-polarization and polarization structure functions of hadrons are obtained. Within the framework of the quark-parton model, all structure functions are determined and spin asymmetries are studied in detail. Keywords: deep inelastic scattering, structure functions, quark-parton model, two-spin asymmetry.
