Abstract

In this paper, we discuss how windows in Euclidean time can be used to isolate the origin of potential conflicts between evaluations of the hadronic-vacuum-polarization (HVP) contribution to the anomalous magnetic moment of the muon in lattice QCD and from e(+)e(-)-> hadronscross-section data. We provide phenomenological comparison numbers evaluated from e(+)e(-)-> hadronsdata for the window ...
