Description
The BABAR Collaboration has an intensive program of studying hadronic
cross sections at low-energy e+e- collisions, accessible at BaBar 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 ~3.5 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. We report here the results of recent studies
with the final states that constitute the main contribution to
the hadronic cross section in the energy region between 1 and 3 GeV,
as e+e- -> K+K-, K0S K0L, and e+e- -> 4 hadrons.
