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 $\Upsilon(5S)$ peak are useful to study bottomonia: we report about the study on the $\Upsilon(5S) \to \Upsilon(1S) K^+ K^-$ channel. Other results from this data sample, including the study of $B^*$ mass and a new measurement of $B_s \to D X$ branching fraction, are covered in this talk.
