1. Measurement of the $B^-\to D^0 \ell^- \bar\nu_\ell$ Branching Fraction in 62.8~fb$^{-1}$ of Belle II data / Philipp Horak ; Christoph Schwanda [BELLE2-CONF-PH-2021-011]
07 October 2021

We report a measurement of the branching fraction of the semileptonic decay \bdlnu (and its charge conjugate) using \mbox{$62.8~\text{fb}^{-1}$} of $\Upsilon(4S)\to B\bar B$~data recorded by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+ e^-$ collider. [...]

3. Search for an invisibly decaying Z' boson and study of particle identification at the Belle II experiment / Paul Feichtinger ; Gianluca Inguglia ; Christoph Schwanda [BELLE2-MTHESIS-2021-003] Presented on 16 03 2021 MSc
Atominstitut (ATI); Institut für Hochenergiephysik (HEPHY) / Vienna
The subject of this thesis is the search for a hypothetical Z' vector boson in events with two muons plus missing energy in the final state (e+e− → μ+μ− (Z' → invisible)) at the Belle II detector, located at the SuperKEKB accelerator in Tsukuba, Japan. [...]
