Results on conventional and exotic charmonium at BaBar

Understand

The B factories provide a unique playground for studying the properties of conventional and exotic charmonium states.

• We present recent results in initial state radiation and two-photon fusion, obtained using the full data set collected by the BaBar experiment.
• Amongst BaBar 's harvest presented in this talk, the determination of the quantum numbers of the X(3915) resonance, a body of concording evidence pointing to JPC = 1++ for the X(3872), and updates on the family of the Y resonance to the full integrated luminosity.
