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


الملخص بالإنكليزية

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 $eta_c$ 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.
