Initial-state radiation measurement of the e+e−→π+π−π+π− cross section

We study the process e+e−→π+π−π+π−γ, with a photon emitted from the initial-state electron or positron, using 454.3  fb−1 of data collected with the BABAR detector at SLAC, corresponding to approximately 260 000 signal events. We use these data to extract the nonradiative σ(e+e−→π+π−π+π−) cross sect...

520 |a We study the process e+e−→π+π−π+π−γ, with a photon emitted from the initial-state electron or positron, using 454.3  fb−1 of data collected with the BABAR detector at SLAC, corresponding to approximately 260 000 signal events. We use these data to extract the nonradiative σ(e+e−→π+π−π+π−) cross section in the energy range from 0.6 to 4.5 GeV. The total uncertainty of the cross section measurement in the peak region is less than 3%, higher in precision than the corresponding results obtained from energy scan data.
