非局域量子电动力学中电子和μ子的泡利形状因子
Pauli form factors of electron and muon in nonlocal quantum electrodynamics
摘要：
在非局域量子电动力学中研究了电子和μ子的泡利形状因子。我们计算了它们的泡利形状因子的单圈QED修正。相对论调节子由非局域相互作用中的关联函数产生。确定了调节器中的截止参数$Λ$，得到了与局域QED水平一致的电子和μ子反常磁矩。当动量转移较大时，非定域QED与定域QED存在明显的差别。
英文摘要：
Pauli form factors of electron and muon are studied in nonlocal quantum electrodynamics. We calculate one loop QED correction to their Pauli form factors. The relativistic regulator is generated by the correlation function in the nonlocal interaction. The cut-off parameter $Λ$ in the regulator is determined to get the consistent anomalous magnetic moments of electron and muon at the same level as local QED. When momentum transfer is large, there exists obvious difference between nonlocal and local QED.
