Hadronic ligh-by-light contribution to the anomalous magnetic moment of the muon: The role of scalar resonances in a holographic model of QCD
We review the evaluation of scalar mesons contribution to the hadronic light-by-light piece of the muon anomalous magnetic moment, using a holographic model of QCD.We evaluate the contributions of the lightest, sub-GeV scalars σ(500), a0(980) and f0(980) and their associated towers of excited states...
