The Belle II experiment collected a 19.2 fb$^{-1}$ sample of data at centre-of-mass energies near the $\Upsilon(10753)$ resonance. We present several results related to the following processes: $e^+e-\to \Upsilon(nS)\eta$, $e^+e-\to \gamma X_b(\chi_{bJ}\pi^+\pi^-)$, and $e^{+}e^{-}\to\chi_{bJ}(1P) \gamma$. These results provide additional information about the nature of the $\Upsilon(10753)$...
Time-integrated and time-dependent measurements of CP violation are important to test the Standard Model (SM) description. In particular, the tree-level determination of the CKM angle gamma is a standard candle measurement of CP violation in the SM. The latest CP violation measurements using beauty to open charm decays from LHCb are presented.
The Belle and Belle II experiments have collected a $1.6~\mathrm{ab}^{-1}$ sample of $e^+e^-$ collision data at centre-of-mass energies near the $\Upsilon(nS)$ resonances. We present a measurement of the $B^{0}$ and $B^+$ meson mass difference and a measurement of $\sigma\left(e^+ e^-\to J/\psi p\bar{p}\right)$ over a range of centre-of-mass energies accessed via initial-state radiation.
