Description
Belle II is the only particle physics experiment at the SuperKEKB $e^+e^-$ asymmetric-energy collider. While SuperKEKB achieved a new world record for peak luminosity, $5.1\times10^{34}\,\textrm{cm}^{-2}\,\textrm{s}^{-1}$, in 2024, the background conditions at the Belle II detector became more challenging compared to previous run periods. In this presentation, we share our experience with dedicated background studies during the 2024 run, as well as the performance of new online monitors equipped with background decomposition capabilities.
