Review of Recent Calculations of the Hadronic Vacuum Polarisation Contribution
Zhiqing Zhang · EPJ Web of Conferences · 2016
Recent calculations of the hadronic vacuum polarisation contribution are reviewed. The focus is put on the leading-order contribution to the muon magnetic anomaly involving e+e− annihilation cross section data as input to a dispersion relation approach. Alternative calculation including tau data is also discussed. The τ data are corrected for various isospin-breaking sources which are explicitly shown source by source.
