abstract = "We study the processes e+e-→2(π+π-)π0π0π0γ and 2(π+π-)π0π0ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469 fb-1. The invariant mass of the hadronic final state defines the effective e+e- center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From the mass spectra, the first ever measurements of the e+e-→2(π+π-)π0π0π0 and the e+e-→2(π+π-)π0π0η cross sections are performed. The contributions from ωπ+π-π0π0, η2(π+π-), and other intermediate states are presented. We observe the J/ψ and ψ(2S) in most of these final states and measure the corresponding branching fractions, many of them for the first time.",

N2 - We study the processes e+e-→2(π+π-)π0π0π0γ and 2(π+π-)π0π0ηγ in which an energetic photon is radiated from the initial state. The data were collected with the BABAR detector at SLAC. About 14 000 and 4700 events, respectively, are selected from a data sample corresponding to an integrated luminosity of 469 fb-1. The invariant mass of the hadronic final state defines the effective e+e- center-of-mass energy. The center-of-mass energies range from threshold to 4.5 GeV. From the mass spectra, the first ever measurements of the e+e-→2(π+π-)π0π0π0 and the e+e-→2(π+π-)π0π0η cross sections are performed. The contributions from ωπ+π-π0π0, η2(π+π-), and other intermediate states are presented. We observe the J/ψ and ψ(2S) in most of these final states and measure the corresponding branching fractions, many of them for the first time.
