提出了一种以规范玻色子、希格斯粒子和费米子的电荷和质量作为物理参数的电弱标准模型的重正化方案。光子经过处理，使得量子电动力学包含为简单的子结构。考虑规范对称性的场重整化给出了有限传播器和顶点函数。非物理扇区的格林函数之间的沃德恒等式允许重整化，从而保持 t'Hooft-Feynman 规范中传播器的简单极结构。我们给出了非物理希格斯粒子和幽灵扇区中的自能量和所有重整化常数的完整列表。给出了重整化自能、顶点函数和进入费米子过程 1 环辐射校正评估的框的显式结果。我们计算了对纯轻子反应的 1 环辐射校正，例如 μ 衰变、vμμe 散射和 e+e−湮灭中的 μ 对产生。通过将这些低能量数据与 W 和 Z 玻色子质量的 PP 对撞机实验结果进行比较来执行标准模型的测试。
A renormalization scheme for the electroweak standard model is presented in which the electric charge and the masses of the gauge bosons, Higgs particle and fermions are used as physical parameters. The photon is treated such that quantum electrodynamics is contained as a simple substructure. Field renormalization respecting the gauge symmetry gives finite propagators and vertex functions. The Ward identities between the Green functions of the unphysical sector allow a renormalization that maintains the simple pole structure of the propagators in the t'Hooft-Feynman gauge. We give a complete list of self energies and all renormalization constants also in the unphysical Higgs and ghost sector. Explicit results are given for the renormalized self energies, vertex functions and boxes that enter the evaluation of 1-loop radiative corrections to fermionic processes. We calculate the 1-loop radiative corrections to purely leptonic reactions like μ decay, vμμe scattering and μ pair production in e+e−annihilation. A test of the standard model is performed by comparing these low energy data with the results of the PP collider experiments for the W and Z boson masses.
