Results on Charmonium and Charmonium-like States at the Belle Experiment

Abstract

New results of the Belle experiment at the KEKB asymmetric e^+e^- collider are presented, in particular (a) measurement of the mass and width of the ${\eta }_c$ and ${\eta }_c^{\prime }$ in B meson decays, (b) measurement of the mass, width and quantum numbers of the X(3872) and (c) observation of the ${\chi }_{c2}$ in $B$ meson decays.

presented at hadron2011, XIV International Conference on Hadron Spectroscopy, Munich, June 13-17, 2011
