Processes of deep-elastic and elastic lepton-nucleon scattering (for both unpolarized and polarized initial particles) are considered. Weinberg-Salam theory . Deep-inelastic and elastic scattering processes of neutrinos and antineutrinos on nucleons (charged and neutral currents) are considered. Detailed description of the parton model. The processes of neutrino scattering on electrons are considered. P-uneven effects in deep-inelastic scattering of leptons by nucleons. are discussed All calculations are very detailed. The book can be useful for those who want to master the technique of calculating sections and asymmetries .. For physicists - theorists and experimenters. May be recommended to graduate students and senior students specializing in particle physics.
