What does Holographic QCD predict for anomalous (g − 2)μ?

In this talk we discuss how holographic models of QCD have been applied to the study of the lightby-light contribution to the muon anomalous magnetic moment. After a review of the holographic procedure, we discuss the approach we followed in a previous work, in which, using a certain set of holographic model as a “Theory Space”, we gave our estimate for the π0 exchange diagram. Our result depended also on the value of the quark magnetic susceptibility. Thus, in the last part of the talk, we concentrate on the attempts which have been done in the literature to apply holographic methods to the evaluation of this important order parameter of QCD.
