Pion Pole Contribution to Hadronic Light-by-Light Scattering and Muon Anomalous Magnetic Moment

We derive an analytic result for the pion pole contribution to the light-by-light scattering correction to the anomalous magnetic moment of the muon, a(mu) = (g(mu)-2)/2. Using the vector meson dominance model for the pion transition form factor, we obtain a(LBL,pi0)mu = +56x10(-11).
