A number of superstring theories predict the existence of an extra new Z′-boson and leptoquarks which may possess massess about 1–10 TeV. We investigate in detail possible manifestations of these particles in polarized e+e− beams on future colliders LEP II and CLIC. We calculate cross-sections and various asymmetries of the processes e+e−→µ+µ−, , ūu taking into account contributions of the Z′-boson and leptoquarks. It is shown that the measurement of the total cross-section σ(e+e−→µ+µ−) is the most sensitive parameter for the existence of Z′-bosons, and the forward-backward asymmetry AFB is that for the existence of leptoquarks.
