We study the processes e+e−→π+π−π0π0π0γ and π+π−π0π0ηγ in which an energetic photon is radiated from initial state. The data are collected with BABAR detector at SLAC. About 14 000 4700 events, respectively, selected a sample corresponding to integrated luminosity of 469 fb−1. invariant mass hadronic final state defines effective e+e− center-of-mass energy. From spectra, first precise measurement e+e−→π+π−π0π0π0 cross section ever e+e−→π+π−π0π0η performed. energies range threshold 4.35 GeV. systematic uncertainty typically between 10% 13%. contributions ωπ0π0, ηπ+π−, other intermediate states presented. observe J/ψ ψ(2S) most these measure branching fractions, many them for time.30 MoreReceived 30 October 2018DOI:https://doi.org/10.1103/PhysRevD.98.112015Published by American Physical Society under terms Creative Commons Attribution 4.0 International license.
