Measurement of the e+e− → π+π− cross section between 600 and 900 MeV using initial state radiation

We extract the e+e−→π+π−e+e−→π+π− cross section in the energy range between 600 and 900 MeV, exploiting the method of initial state radiation. A data set with an integrated luminosity of 2.93 fb−12.93 fb−1 taken at a center-of-mass energy of 3.773 GeV with the BESIII detector at the BEPCII collider...
