左右对称复合模型中的反常μ子磁矩

Anomalous muon magnetic moment in a left-right symmetric composite model

Piyali Banerjee

摘要:

本文计算了已知标准模型轻子的激发态左右对称激发轻子在一圈能级上产生的μ子反常磁矩。这种激发态出现在复合理论中,在复合理论中,已知的轻子被假定是由更基本的粒子组成的。在本工作中,我们假设激发态轻子也具有左右对称性。我们发现在单圈水平上,QED对这些激发轻子的μ子反常磁矩的贡献仅来自一个费恩曼图,这是标准模型中唯一对μ子反常磁矩有贡献的费恩曼图的自然模拟。

英文摘要:

We calculate the anomalous magnetic moment for muons at one loop level arising from left right symmetric excited leptons which are excited states of known standard model leptons. Such excited states arise in compositeness theories where the known leptons are assumed to be made of more fundamental particles. In this work, we assume that the excited leptons possess a left right symmetry also. We show that at the one loop level, the QED contribution to the muon anomalous magnetic moment from these excited leptons comes from only one Feynman diagram, which turns out to be a natural analog of the only diagram contributing to anomalous muon magnetic moment in the Standard Model.
