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 of the processes e+e- -> K+K-, and e+e- -> 4 hadrons,
which constitute the main contribution to the hadronic cross
section in the energy region between 1 and 3 GeV.
