Description

The large data sample accumulated by the Belle experiment at KEKB asymmetric energy $e^{+}{e}^{-}$ collider provides an important opportunities to study charmonium(-like) and bottomonium(-like) states. We report new results on $X(3872)$ decays to $J/\psi \omega$ and ${\pi }^{+}{\pi }^{-}{\pi }^0$ final states, as well as other studies on charmonium. Belle data taken with an energy scan around the $\mathrm{{\rm Y}}(5S)$ peak are useful to study bottomonia: we report about the study on the $\mathrm{{\rm Y}}(5S)\to \mathrm{{\rm Y}}(1S)K^{+}{K}^{-}$ channel. Other results from this data sample, including the study of $B^{\ast }$ mass and a new measurement of $B_s\to DX$ branching fraction, are covered in this talk.
