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 $e^{+}{e}^{-}\to {\pi }^{+}{\pi }^{-}{\pi }^0{\pi }^0{\pi }^0$, e^+e^- \to \pi^+\pi^-\pi^0\pi^0\eta$,and$e^+e^- \to \pi^+\pi^-\eta$.Thesefinalstatesarestudiedinawidemassrange,fromthresholdproductionupto4GeV/$c^2$.
