Hadronic vacuum polarization and light-by-light scattering in representative infrared-improved soft-wall holographic QCD models

Jin-Yang Shen, Wen-Yuan Peng, Ling-Yun Dai +1

We investigate the hadronic contributions to the anomalous magnetic moment of the muon $a_{\mu }$ in three representative infrared-improved soft-wall AdS/QCD models, focusing on the lea…
