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…

Hadronic light-by-light contribution to the muon g−2 from holographic QCD with massive pions
We extend our previous calculations of the hadronic light-by-light scattering contribution to the muon anomalous magnetic moment in holographic QCD to models with finite quark masses and a tower of
ON DISPERSION RELATIONS AND HADRONIC LIGHT-BY-LIGHT SCATTERING CONTRIBUTION TO THE MUON ANOMALOUS MAGNETIC MOMENT
We discuss the use of dispersion relations for the evaluation of the pseudoscalar contributions to the muon anomalous magnetic moment. We point out that, in the absence of experimental data,
Pseudo scalar contributions to light-by-light correction of muon g−2 in AdS/QCD
Abstract We have performed a holographic calculation of the hadronic contributions to the anomalous magnetic moment of the muon, using the gauge/gravity duality. As a gravity dual model of QCD with
Short-distance constraints for the HLbL contribution to the muon anomalous magnetic moment
We derive short-distance constraints for the hadronic light-by-light contribution (HLbL) to the anomalous magnetic moment of the muon in the kinematic region where the three virtual momenta are all

TLDR
For the first time, the form factor that yields the light-by-light scattering contribution to the muon anomalous magnetic moment is computed in such a framework, lattice QCD+QED and QED, and initial results are promising.

We review the current status of theoretical calculations of the hadronic light-by-light scattering contribution to the muon anomalous magnetic moment. Different approaches and related issues such as
Theta dependence in holographic QCD
A bstractWe study the effects of the CP-breaking topological θ-term in the large Nc QCD model by Witten, Sakai and Sugimoto with Nf degenerate light flavors. We first compute the ground state energy
Light scalar mesons in the soft-wall model of AdS/QCD
We study light scalar mesons in the holographic QCD soft-wall model with a background dilaton field. The masses and decay constants are compatible with experiment and QCD determinations if a{sub
Quark mass deformation of holographic massless QCD
We propose several quark mass deformations of the holographic model of massless QCD using the D4/D8/-brane configuration proposed by Sakai and Sugimoto. The deformations are based on introducing
