Abstract

We review the recent progress made in using holographic QCD to study hadronic contributions to the anomalous magnetic moment of the muon, in particular the hadronic light-by-light scattering contribution, where the short-distance constraints associated with the axial anomaly are notoriously difficult to satisfy in hadronic models. This requires the summation of an infinite tower of axial vector mesons, which is naturally present in holographic QCD models, and indeed takes care of the longitudinal short-distance constraint due to Melnikov and Vainshtein. Numerically the results of simple hard-wall holographic QCD models point to larger contributions from axial vector mesons than assumed previously, while the predicted contributions from pseudo-Goldstone bosons agree nicely with data-driven approaches.

摘要

我们回顾了利用全息量子色动力学研究强子对μ子反常磁矩的贡献方面的最新进展，特别是强子轻子轻子散射贡献，其中与轴矢反常相关的短程约束在强子模型中极难满足。这需要对无穷多的轴矢介子塔进行求和，而这在全息量子色动力学模型中是自然存在的，并且确实解决了梅尔尼科夫和瓦因施泰因提出的纵向短程约束问题。从数值上看，简单的硬壁全息量子色动力学模型的结果表明，轴矢介子的贡献比之前假设的要大，而赝戈德斯通玻色子的预测贡献与数据驱动方法的结果吻合得很好。
