Content

The BABAR Collaboration has an extensive program studying hadronic cross sections in low-energy e+e- collisions, accessible through the selection of events with initial-state photon radiation. The measurements allow significant improvements in the precision of the standard model prediction for the muon anomalous magnetic moment. Recent results on the pi+pi-pi0pi0 final state and on KKpipi final states are presented. The pipipipi channel is one of the most important for the muon g-2 calculation, while our measurements of the KKpipi channels obviate the need to rely on isospin relations and greatly improve the results in these channels.
