In this thesis, first we give a brief review on two versions of noncommutative standard model (NCSM) which are : ü NCSM based on SU(3) SU(2) U(1) gauge group and Seiberg-Witten maps for the field contents of the theory. ü NCSM based on U * (3) U * (2) U * (1) gauge symmetry which can be reduced to the standard gauge group by an appropriate Higgs mechanism. Then we complete the Seiberg-Witten maps for the Higgs and non-Abelian gauge filds up to second order of the parameter of noncommutativity, . We extend the noncommutative standard model based on the minimal SU(3) SU(2) U(1) gauge group to . Consequently we calculate the
