Study of the reaction e+e− → J/ψπ+π− via initial-state radiation at BABAR

We study the process e + e − → J / ψ π + π − with initial-state-radiation events produced at the PEP-II asymmetric-energy collider. The data were recorded with the BABAR detector at center-of-mass energies 10.58 and 10.54 GeV, and correspond to an integrated luminosity of 454     fb − 1 . We investi...
