Abstract

A e+e− → π+π−π0 visible cross section is measured with the radiative return method over 0.73 ≤ √s < 3.5 GeV, using 526.6 fb−1 of Υ(4S) data collected with the Belle detector at the KEKB asymmetric-energy e+e− collider. This measurement provides an important check on the newer SND and BABAR e+e− → π+π−π0 cross section measurements that conflict with the older ND and DM2 measurements. This measurement will contribute to the reduction in error for the Standard Model calculations of the muon anomalous magnetic moment and the running of α, while also contributing to the field of hadron spectroscopy.
