Speaker
Description
Since the discovery of X(3872), Belle has been pioneering the exploration
of tetraquarks, QCD bound states beyond standard mesons and baryons. More
than a decade after the end of data taking, the Belle datasets are still
producing results in hadron spectroscopy, and have provided the
motivations for the first energy scan above the energy of the $\Upsilon(4S)$ peak, between 10.65 GeV and 10.81 GeV, taken by Belle II in November 2022. This talk will present recent results on searches for the hidden bottom transitions between $\Upsilon$(10750) and lower bottomonia, and measurements of the energy dependence of the $e^+e^-\rightarrow B^{(*)}\bar{B}^{(*)}$ cross section. In addition, we will show results of a search for resonant double charmonium bound states, done with Belle data, which gives insights on our future opportunities on this topic.
