Contribution
It introduces a holographic method for computing the hadronic vacuum polarization contribution to muon g-2, using AdS/QCD with two light flavors.
Findings
Calculated amu(HLO) = 470.5 x 10^{-10} using holography.
Results are consistent with experimental estimates from BABAR data.
Demonstrates the viability of holographic methods in precision QCD calculations.
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}.
