论文摘要
我们评估了在最小的硬壁和软壁全息QCD模型中，在最小的硬壁和软壁全息模型中以及与其简单的概括中评估了哑光的异常磁矩，并与分散和晶状体接近可获得的相当精确的结果相比，具有两种光明的磁力力矩。尽管不能期望全息QCD阐明后者之间现有的小差异，但此比较又提供了有关全息模型的有用信息，这些模型已用于评估hadronic sight of Light wight wight wight wight wight of lightight wight primy primy primits promint of-light wight that-priend和lattice方法中的错误。特别是，在最近被用来实现hadronic逐光贡献的Melnikov-vainshtein短途限制的硬壁模型中，Hadrononic真空极化与数据驱动的方法点的匹配点匹配了最近提出的参数校正的方法，以考虑到次要到临近的序列效果。
We evaluate the leading-order hadronic vacuum polarization contribution to the anomalous magnetic moment of the muon with two light flavors in minimal hard-wall and soft-wall holographic QCD models, as well as in simple generalizations thereof, and compare with the rather precise results available from dispersive and lattice approaches. While holographic QCD cannot be expected to shed light on the existing small discrepancies between the latter, this comparison in turn provides useful information on the holographic models, which have been used to evaluate hadronic light-by-light contributions where errors in data-driven and lattice approaches are more sizable. In particular, in the hard-wall model that has recently been used to implement the Melnikov-Vainshtein short-distance constraint on hadronic light-by-light contributions, a matching of the hadronic vacuum polarization to the data-driven approach points to the same correction of parameters that has been proposed recently in order to account for next-to-leading order effects.
