New results on charmonium like states at Belle
New results on charmonium-like states measured by the Belle experiment at the KEKB asymmetric e + e - collider are presented, in particular (a) Search for the Z c pair production in $\Upsilon (1{\rm{S}}),\,\Upsilon (2S)$ decays and in e + e - $\sqrt s $ of 10.52, 10.58, and 10.867 GeV. (b) Measureme...
