Description
A recent benchmark lattice calculation of the isovector elastic
pion-pion scattering amplitude and corresponding timelike pion form factor is
presented. Systematic errors due to the lattice spacing and finite volume are demonstrably
controlled, paving the way for phenomenological applications. For example, the
timelike pion form factor contributes significantly to lattice determinations
of the hadronic vacuum polarization contribution to the anomalous magnetic
moment of the muon.
