Description
The measurement of exclusive $e^+e^-$ to hadrons processes is a significant part of the physics program of BABAR detector, aimed to improve the calculation of the hadronic contribution to the muon $g−2$ and to study the intermediate dynamics of the processes. 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 $e^+e^- \to \pi^+\pi^-\eta$,
which have been studied in a wide mass range, from threshold production up to 4 GeV/$c^2$.
