Description

The Belle II experiment has collected a 364 $f{b}^{-1}$ sample of $e^{+}{e}^{-}$ collisions at the $\mathrm{{\rm Y}}(4S)$ resonance. This dataset, with its low particle multiplicity and well-constrained initial state, provides an ideal environment for studying semileptonic and missing energy $B$ decays. In this talk, I will present recent results on these decays, emphasizing their impact on the determination of CKM matrix elements and potential new physics. I will also discuss the techniques used for missing energy reconstruction and the challenges of signal-background discrimination. Future analysis prospects with larger data sets will also be highlighted.
