Abstract

Deep inelastic scattering of neutrinos and antineutrinos by polarized protons is considered in the quark-parton model. For processes with charged currents, a connection is obtained between the asymmetry of the differential cross sections corresponding to different spin directions of the target proton and the distribution functions of the polarized partons in the polarized proton (d for neutrinos and u for antineutrinos). It is shown that the presence of an x dependence of the asymmetry parameter corresponds to a difference between the distribution functions of partons with opposite helicity. For processes with neutral currents, relations are obtained between the asymmetry parameters and the constants that determine the helicity structure of the weak neutral quark current.
