讨论了μ子反常磁矩的电弱辐射修正的现状。本文给出了几种重要的电弱双圈顶夸克三角图的渐近展开式，并将其推广到高阶。结果进行了比较，更一般的积分表示解决方案一般费米子三角形圈耦合到任意质量的赝标和标量玻色子。此外，良好的协议被发现比预期范围更广的质量参数。
The current status of electroweak radiative corrections to the muon anomalous magnetic moment is discussed. Asymptotic expansions for some important electroweak two-loop top quark triangle diagrams are illustrated and extended to higher order. Results are compared with the more general integral representation solution for generic fermion triangle loops coupled to pseudoscalar and scalar bosons of arbitrary mass. Furthermore, excellent agreement is found for a broader than expected range of mass parameters.
