Holographic calculation of hadronic contributions to muon g-2
Abstract
Using the gauge/gravity duality, we compute the leading order hadronic (HLO) contribution to the anomalous magnetic moment of muon, amu(HLO). Holographic renormalization is used to obtain a finite vacuum polarization. We find amu(HLO) =470.5 x 10-10 in AdS/QCD with two light flavors, which is compared with the currently revised BABAR data estimated from e+ e- -> pi+ pi- events, amu(HLO)[pipi]=(514.1 +- 3.8) x 10-10.
