Поляризационные асимметрии неупругого рассеяния в рамках калибровочных моделей c дополнительным нейтральным бозоном

Abstract

New types of electroweak asymmetries of deep inelastic scattering of polarized leptons with energies of 2-2000 GeV by polarized nucleons were calculated and analyzed in the quark-parton model. The results are obtained in framework of Standard Model and a set of gauge models of electroweak interaction with additional Z-boson. The comparison of asymmetries demonstrates that the difference in the results of gauge models increases with the energy of incidence scattering photons and reaches its maximal value for the largest possible scaling variable y.
