Description

Production of fermion partner scalar pair at annihilation of arbitrary polarized electrons and positions is investigated in SU(2)xU(1), SU(2)LxSU(2)RxU(1) and SU(3)xU(1) gauge models. Different electroweak asymmetries (ARL right-left asymmetry, A1 P-even transverse spin asymmetry and A2 P-odd asymmetry) at √s=40-360 GeV e--e+ beam energy and 0.21≤sin2Θw≤0.27 values of Weinberg parameter are determined and analyzed in detail. The conducted calculations show, that presence of weak neutral currents results in noticeable electroweak asymmetries and these asymmetries are sensitive to the selection of the gauge model
