Description
A program of measuring the light hadrons production in exclusive e+e -> hadrons
processes is continuing with the BABAR data, 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 -> pi+pi-pi0pi0, pi+pi-pi0pi0pi0(eta), e+e-> pi_pi-eta. Additionally, we
present the study of the two-photon process e+e- -> e+e-eta(958) in the
double-tag mode. The results for the form factor are compared with the
predictions based on pQCD and VMD.
