Özet
Using initial-state radiation events from a total integrated luminosity of 11.957 fb-1 of e thorn e- 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 e thorn e- -> AA over bar is measured in 16 AA over bar invariant mass intervals from the production threshold up to 3.00 GeV=c2. The results are consistent with previous results from BABAR and BESIII, but with better precision and with narrower AA over bar invariant mass intervals than BABAR.
