Полуинклюзивное глубоконеупругое рассеяние (анти)нейтрино на поляризованных мишенях

Abstract

Asymmetries for the semi-inclusive deep inelastic scattering (anti (neutrino on polarized targets with a charged weak current have been obtained for the case of я-mesons production. It was obtained in the terms of the quarkarton model and in the Born approach. These asym­ metries do not depend on the functions of fragmentation of я-mesons. The contributions of quark flavours and valency quarks to the spin of nucleon have been determined.
