Two recent studies from the BABAR experiment at SLAC on low-energy hadronic final states in e+e− annihilations are presented. The first study provides the first-ever measurement of the γ*γ*→ η' transition factor, where γ* denotes an oﬀ-shell photon. The second study provides the first-ever measurements of the e+e−→ π+ π−π0π0π0 and π+π−π0π0η cross sections, including studies of the intermediate resonance states and the corresponding J/ψ and ψ(2S) branching fractions.
