We calculate the total and differential cross sections for the process e+e- →W+W- taking into account the extra Z-boson (ZE) predicted by the E8 ⊗E8' superstring theory. It is pointed out that around the pole of ZE the cross sections are very sensitive to the value of the new mixing angle θE between Z0 (ordinary Z-boson) and ZE and that the obsevation of the cross sections is critical to determine the relative sign between θE and the Weinberg angle θW.
