Abstract: The discrepancy between the standard model prediction for the muon  anomalous magnetic moment and the experimental result is accompanied by other anomalies.  A crucial input for the prediction is the hadronic vacuum polarization inferred from hadronic data. However, the two most accurate determinations  from KLOE and BaBar disagree by almost 3 sigma. Additionally, the combined data-driven result also disagrees with the  most precise lattice determination.  We show that all these discrepancies could be accounted for by a new boson produced resonantly around  the  KLOE  centre  of  mass  energy and decaying promptly  yielding lepton pairs in the final states. We then present a simple model that can reconcile the  KLOE and BaBar results, the data-driven and the lattice SM predictions, and eventually the predicted and measured values of the muon  anomalous magnetic moment, while complying with all phenomenological constraints.
