e+e- → π+π -π+π-, K+K -π+π-, and K+K -K+K- cross sections at center-of-mass energies 0.5-4.5 GeV measured with initial-state radiation

e+e- → π+π -π+π-, K+K -π+π-, and K+K -K+K- cross sections at center-of-mass energies 0.5-4.5 GeV measured with initial-state radiation

We study the process e+e- → π+π -π+π-γ, with a hard photon radiated from the initial state. About 60 000 fully reconstructed events have been selected from 89 fb-1 of BABAR data. The invariant mass of the hadronic final state defines the effective e+e- e +e- center-of-mass energy, so that these data...
