摘要：
Contributions of fermion loops, W-boson loops and their sum to the high energy gamma gamma --> gamma gamma scattering total cross section (\cos theta\ < cos30<degrees>) are calculated numerically by using the analytic expressions of gamma gamma --> gamma gamma 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.
