Description
A program of measuring the light hadrons production in exclusive e+e− \to hadrons processes is in place at BABAR, with the aim to improve the calculation of the hadronic contribution to the muon g−2. We present the most recent results 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. In particular, we report the results on the channels e+e−→π+π−π0π0, pi+pi-pi0pi0pi0(η), e+e−→π+π−η. Additionally, 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.
