Description

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 $\pi^+\pi^-\pi^0\pi^0$ final state and on $KK\pi\pi$ final states are presented. The $\pi\pi\pi\pi$ channel is one of the most important for the muon g-2 calculation, while our measurements of the $KK\pi\pi$ channels obviate the need to rely on isospin relations and greatly improve the results in these channels.
