Effects of neutral weak currents in scattering of polarized leptons on polarized nucleons in non-minimal gauge models

Polarizational, charge-polarizational and charge electroweak asymmetries in deep-inelastic scattering of ultrarelativistic polarized leptons with energies of 10-500 GeV on polarized nucleons are considered in the quark-parton model and within the framework of gauge models of electroweak interactions with the symmetry groups SU(2)xU(1), SU(3)xU(1), SU(2)sub(L)xSU(2)sub(R)xU(1). It is found that for all types of electroweak asymmetries, except the charge asymmetries with positive helicity of the initial lepton, the results of the SU(3)xU(1) and SU(2)sub(L)xSU(2)sub(R)xU(1) models are similar, being appreciably different from those of the standard model. The difference in the results increases with the energy of incident leptons and reaches its maximum for largest possible values of x and y
