英文摘要: Based on a systematic analysis of the renormalization schemes in the general R(xi) gauge, the precise formulation of the equivalence theorem for longitudinal weak boson scatterings is given both in the SU(2)L Higgs theory and in the realistic SU(2) x U(1) electroweak theory to all orders in the perturbation for an arbitrary Higgs boson mass m(H). It is shown that there is generally a renormalization-scheme- and xi dependent modification factor C(mod) and a simple formula for C(mod) is obtained. Furthermore, a convenient particular renormalization scheme is proposed in which C(mod) is exactly unity. Results of C(mod) in other currently used schemes are also discussed especially on their xi and m(H) dependence through explicit one-loop calculations. It is shown that in some currently used schemes the deviation Of C(mod) from unity and the xi dependence of C(mod) are significant even in the large-m(H) limit. Therefore care should be taken when applying the equivalence theorem.
