New Charmonium-Like States at Babar and Belle

Abstract

BaBar and Belle have recently revived the interest in charmonium spectroscopy, discovering many unexpected resonances. In this review, I'll focus mostly on the states found in B decays and double $\ccbar$. A better understanding of their production mechanism can help to discriminate among models, confirm tentative $J^{PC}$ assignments, and clarify the overall picture.
