Abstract

We report the results on the channels e⁺e⁻→ π⁺π⁻π⁰π⁰π⁰(η), e⁺e⁻→ π⁺π⁻η. Also we present the study of the two-photon process e⁺e⁻→ e⁺e⁻η^' in the double-tag mode. The results for the form factor are compared with the predictions based on pQCD and VMD. The results are obtained by using the full data set of about 470 fb⁻¹ collected by the BABAR experiment at the PEP-II e⁺e⁻collider at a center-of-mass energy of about 10.6 GeV.
