### Description

The measurement of exclusive $e^+e^-$ to hadrons processes is a significant part of the physics program of BABAR experiment, 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 studies performed on the full data set of about 470 fb$^{−1}$ collected 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 $e^+e^-$ annihilation into three pions and into states with six and seven pions or kaons, in an energy range from production threshold up to about 4 GeV.
