Abstract：
Contributions of fermion loops,W-boson loops and their sum to the high energyγγ→γγ scattering total cross section (｜cosθ｜<COS30)are calculated numerically by using the analytic expressions ofγγ→γγ scattering helicity amplitude from previous paper.These contributions may be observed in the future Photon Linear Collider,and may be used to test standard model.
