Abstract
Using initial-state radiation events from a total integrated luminosity of 11.957 fb of collision data collected at center-of-mass energies between 3.773 and 4.258 GeV with the BESIII detector at BEPCII, the cross section for the process is measured in 16 invariant mass intervals from the production threshold up to 3.00 GeV. The results are consistent with previous results from BaBar and BESIII, but with better precision and with narrower invariant mass intervals than BaBar.
