Abstract

The ISR method has been largely exploited by the BABAR experiment, for\nmeasuring numerous channels of the cross section e+e- into hadrons. For the\npi+pi-(gamma) and K+K-(gamma) channels, BABAR has pioneered the method based on\nthe ratio between the hadronic mass spectra and the mu+mu-(gamma) one. This\nmethod allows to cancel many systematic uncertainties in the ratio, hence the\nprecise measured cross sections. Many multihadronic channels have also been\nstudied using the ISR method, and cross sections have been published. These\nexperimental results have also been exploited for phenomenological studies,\nlike the determination of the hadronic contribution to the anomalous magnetic\nmoment of the muon (g-2)_mu.\n
