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 $e^+e^- \to \pi^+\pi^-\eta$. These final states are studied in a wide mass range, from threshold production up to 4 GeV/$c^2$.
