本文回顾了硬壁AdS/QCD模型对强子光-by-光散射的预测，并引入张量介子以满足短距离约束，模型与BELLE和BESIII数据吻合良好，从而有助于解释缪子$g-2$异常。
AI 中文摘要
我们简要回顾了硬壁AdS/QCD模型中全息QCD对赝标量和轴矢量介子对强子光-by-光振幅及随之而来的缪子反常磁矩贡献的预测，这使得在纯强子模型中能够满足Melnikov-Vainshtein约束。此外，我们讨论了张量介子在满足剩余短距离约束中的作用，并提供了一个最小张量介子模型的细节，该模型与BELLE的现有数据以及BESIII的初步低$Q^2$数据 remarkably 吻合。在附录中，我们还提供了hQCD中短距离极限的解析结果，并与无质量夸克圈给出的领头阶OPE结果进行了比较。
英文摘要
We briefly review the predictions of holographic QCD in hard-wall AdS/QCD models for the contribution of pseudoscalars and axial-vector mesons to the hadronic light-by-light amplitude and consequently to the muon anomalous magnetic moment, which allows one to satisfy the Melnikov-Vainshtein constraint in a purely hadronic model. Moreover, we discuss the role of tensor mesons in satisfying the remaining short-distance constraints, and provide details for a minimal model of tensor mesons that turns out to agree remarkably well with available data from BELLE as well as preliminary low-$Q^2$ data from BESIII. In an appendix, we also provide analytical results for the short-distance limits in hQCD and compare with the leading-order OPE result as given by the massless quark loop.
