Large mass, non-relativistic dynamics, large energy level spacing and clear
experimental signature are unique characteristics of the bottomonium states
that make this sector so rich with a wide range of opportunities for new
studies, ranging from the the spin structure of QCD to the extensions of the SM
Lagrangian, from the non-$q\bar{q}$ states and light quarks dynamics to the
gluon fragmentation functions.
Experimentally only high-luminosity $e^+e^-$ colliders with $\sqrt{s} > 9$ GeV
can collect enough statistics to study this system in details fully exploiting
its potential. For this reason the BelleII experiment at Super-KEKB collider
offers the most promising prospects for the study of this sector in the next
We will here review the opportunities offered by data taking periods at the
$\Upsilon(3S)$, $\Upsilon(5S)$ and $\Upsilon(6S)$ energies, focusing on the
variety of studies that can be conducted using bottomonium annihilations: study
of conventional and exotic quarkonoium spectroscopy, the search for new physics
in rare decays of heavy mesons, the study of the light scalar meson family
using di-pion transitions among bottomonia, and study of QCD bound states like
deuteron and di-baryons with astrophysics implications.
