摘要：

研究了一个由量子圈图通过对称破缺产生W、Z玻色子和费米子质量的电弱模型。该模型是基于正则化的量子场论，其中的量子圈图是有限的所有阶微扰理论和无质量理论是规范不变，庞加莱不变，和酉。电弱对称性SU（2）X U（1）的破缺是在没有希格斯粒子的情况下实现的。一个~542 GeV的基本能量标度（不要与朴素的截止值混淆）通过费曼环图的正则化进入理论。该理论产生的W质量的预测是准确的约0.5%，没有辐射校正。由于顶点处耦合常数的变化对振幅的抑制，WW -> WW和e+e- -> WW过程的散射振幅在高能时不违反幺正性。

英文摘要：

An electroweak model in which the masses of the W and Z bosons and the fermions are generated by quantum loop graphs through a symmetry breaking is investigated. The model is based on a regularized quantum field theory in which the quantum loop graphs are finite to all orders of perturbation theory and the massless theory is gauge invariant, Poincare invariant, and unitary. The breaking of the electroweak symmetry SU(2) X U(1) is achieved without a Higgs particle. A fundamental energy scale of ~542 GeV (not to be confused with a naive cutoff) enters the theory through the regularization of the Feynman loop diagrams. The theory yields a prediction for the W mass that is accurate to about 0.5% without radiative corrections. The scattering amplitudes for WW -> WW and e+e- -> WW processes do not violate unitarity at high energies due to the suppression of the amplitudes by the running of the coupling constants at vertices.
