Description

The BABAR Collaboration has an intensive program  studying hadronic cross sections in
low-energy e+e- annihilations, accessible via initial-state radiation.
Our measurements allow significant improvements in the precision of the
predicted value of the muon anomalous magnetic moment.
These improvements are necessary for shedding light on the current ~3 sigma
difference between the predicted and the experimental values.
We have published results on a number of processes with two to six hadrons in the final state, and other final state are currently under investigation.
We report here on the most recent results obtained by analysing the entire BABAR dataset.
