Abstract
Belle II offers unique possibilities for discovering and interpreting exotic multiquark bound states
to probe the fundamentals of QCD. We present recent results obtained on a unique data set collected
at energies above the $\Upsilon(4π)$, including searches for the hidden bottom transition between $π (10750)$
and $\chi_{ππ½} (1π)$ and the measurement of the energy dependence of the $e^+e^β \to b\overline{b}$ cross section.

Metadata are provided both in "article" format (very similar to INSPIRE) as this helps creating
very compact bibliographies which can be beneficial to authors and
readers, and in "proceeding" format
which is more detailed and complete.
