摘要:

本文给出了束缚在核势中的μ子的$g$因子的理论描述。精确地考虑了与束缚势的相互作用,计算了单圈自能修正和多圈真空极化修正。结合μ子$g$因子的核效应也进行了评估。提出了利用连续Stern-Gerlach效应测量束缚μ子的$g$因子作为确定自由μ子磁矩异常和质量的独立手段。提出的方案能够提高质量的精度超过一个数量级。

英文摘要:

A theoretical description of the $g$ factor of a muon bound in a nuclear potential is presented. One-loop self-energy and multi-loop vacuum polarization corrections are calculated, taking into account the interaction with the binding potential exactly. Nuclear effects on the bound-muon $g$ factor are also evaluated. We put forward the measurement of the bound-muon $g$ factor via the continuous Stern-Gerlach effect as an independent means to determine the free muons magnetic moment anomaly and mass. The scheme presented enables to increase the accuracy of the mass by more than an order of magnitude.
