چکیده

In Ref. [1] the BESIII collaboration published a cross section measurement of process e+e−→π+π− in energy range between 600 and 900 MeV. this corrigendum, we report corrected evaluation statistical errors terms fully propagated covariance matrix. The correction also yields reduced uncertainty for hadronic vacuum polarization contribution to anomalous magnetic moment muon, which now reads as aμππ,LO(600−900MeV)=(368.2±1.5stat±3.3syst)×10−10. central values aμππ,LO, well systematic uncertainties remain unchanged.

Measurement of the near-threshold e+e- --> D(*)+/-D(*)-/+ cross section using initial-state radiation.

We report a measurement of the exclusive e+e- -->D(*)+/-D*-/+ cross section as a function of center-of-mass energy near the D(*)+/-D*-/+ threshold with initial-state radiation. A partial reconstruction technique is used to increase the efficiency and to suppress background. The analysis is based on a data sample collected with the Belle detector with an integrated luminosity of 547.8 fb(-1).
