Description
Quarkonium resonances and quarkonium-like states provide great information and insights on strong interactions of quarks and gluons. The Belle experiment has collected world's largest event sample of Y(1S), Y(2S), Y(4S) and Y(5S) decays using energy-asymmetric e+ e- collision at KEKB collider. In this talk we present recent results on b b-bar and c c-bar quarkonium spectroscopy and exotic quarkonium-like states from Belle.
