Quarkonium Production and Decay

Abstract

With new data sets, recently completed analyses and renewed interest, there has been significant progress in addressing existing questions about quarkonia production and decay ... but also new questions and new confrontation with theory. Some highlights include the firm establishment of the eta_c^' and of the ``missing'' psi^' decays to pseudoscalar-vector final states, improved information on the nature of the psi(3770), and the observation of a new, puzzling charmonium-like state at 3872 MeV.
