Description
The Belle II experiment at the SuperKEKB energy-asymmetric $e^+ e^-$ collider is a substantial upgrade of the $B$ factory facility at the Japanese KEK laboratory. Since the year 2019, Belle II has recorded close to 600 fb$^{-1}$ at the center-of-mass energy of the $\Upsilon(4S)$ resonance. Together with the Belle data set, this is by far the world-largest sample of electron positron collision events at the $B\bar B$ threshold and allows measurements in the heavy flavour sector with unprecedented precision.
In this presentation, we will review the status of the Belle II experiment and showcase new results on $B$ meson and $\tau$ lepton decays.
