摘要

应用单光子近似下电磁相互作用的影响研究了电弱相互作用中的介子衰变。在此过程中产生的散度是低能区的红外散度。采用最小质量法和量纲正则化法进行离散处理。结果，计算了介子电弱衰变率的电磁校正。我们得到的结果证实了弱相互作用的费米理论是一个不可重整的理论。

ELECTROMAGNETIC CORRECTION IN THE MUON DECAY

The influence of electromagnetic interaction in one photon approximation was applied to study the muon decay in electroweak interaction. The divergences that ariose in this process were infrared ones in the low energy region. The divergent treatment was carried out with two methods: the minimum mass method and the dimensional regularization method. As a result, an electromagnetic correction was calculated for the muon electroweak decay rate. The results that we received confirm that the Fermi theory of weak interaction is a non-renormalizable theory.
