Abstract
To further investigate the applicability of the projection scheme for eliminating the unphysical divergence s/me2 due to U(1) gauge invariance violation, we study the process e-+W+ e-+ t+b which possesses advantages of simplicity and clearness. Our study indicates that the projection scheme can indeed eliminate the unphysical divergence s/me2 caused by the U(1) gauge invariance violation and the scheme can apply to very high energy region.
