Abstract

The large data sample accumulated by the Belle experiment at KEKB asymmetric energy e+ee^+ e^- collider provides opportunities to study charmonia (bottomonia) and charmonium-like (bottomonium-like) exotic particles. In this review, we report recent results on these topics from Belle, including searches for BhcKB\to h_c K, BY(4260)KB\to Y(4260)K, BX(3872/3915)(χc1π0)KB\to X(3872/3915) (\to \chi_{c1} \pi^0 ) K, B0X(3872)γB^0 \to X(3872) \gamma, e+eγχcJe^+e^- \to \gamma \chi_{cJ} and a new measurement of the e+eΥ(nS)π+π(n=1,2,3)e^+ e^-\to \Upsilon(nS) \pi^+ \pi^- (n=1,2,3) cross sections at energies from 10.52 to 11.02 GeV.
