Recent Results on Charmonia- and Bottomonia-like Particles at Belle

Abstract

The large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^{+}{e}^{-}$ 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 $B\to h_{c}K$, $B\to Y(4260)K$, $B\to X(3872/3915)(\to {\chi }_{c1}{\pi }^0)K$, $B^0\to X(3872)\gamma$, $e^{+}{e}^{-}\to \gamma {\chi }_{cJ}$ and a new measurement of the $e^{+}{e}^{-}\to {\rm Y}(nS){\pi }^{+}{\pi }^{-}(n=1,2,3)$ cross sections at energies from 10.52 to 11.02 GeV.
