Abstract

In this study, the cross section ,   of the interaction i i e e      ; (i  , )was calculated .The effect of the weak mixing angle 2 sin w  on the cross section ,   of the same reaction in the energy field89GeV  S  94GeV was also studied. The effect of the center mass energy s on the cross section ,   was also studiedfor two boundary values of the weak mixing angle 2 sin w  : 0.23221 , 0.2233. The study showed that the effect of the weak mixing angle on the sectional difference , (nb)    gets in the energy field s  (911)GeV , and takes a maximum value almost equal to the mass of the Z- boson .
