University of Sydney / Sydney
Precision measurements of the magnitudes of the Cabibbo-Kobayashi-Maskawa (CKM)-matrix elements, which characterise the transitions between quarks of different flavours, are essential for testing the unitarity of the Unitarity Triangle (UT) described by the Standard Model. [...]

2. Reconstruction of B→ρℓνℓ decays identified using hadronic decays of the recoil B meson in 2019 -- 2021 Belle II data / Moritz Bauer ; Nadia Ejlal Toutounji ; Pablo Goldenzweig ; Kevin Varvell [BELLE2-CONF-DRAFT-2022-029] [BELLE2-CONF-PH-2022-029]
29 November 2022

We present results on the semileptonic decays $B^0 \to \rho^- \ell^+ \nu_\ell$ and $B^+ \to \rho^0 \ell^+ \nu_\ell$ in a sample corresponding to 189.9/fb of Belle II data at the SuperKEKB $e^- e^+$ collider [...]

3. Study of Exclusive $B \to \pi e^+ \nu_e$ Decays with Hadronic Full-event-interpretation Tagging in 189.3 fb$^{-1}$ of Belle II Data / Nadia Toutounji ; Moritz Bauer ; Pablo Goldenzweig ; Kevin Varvell [BELLE2-CONF-PH-2022-008]
16 June 2022

We present a reconstruction of the semileptonic decays $B^0 \to \pi^- e^+ \nu_e$ and $B^+ \to \pi^0 e^+ \nu_e$ in a sample corresponding to 189.3 fb$^{-1}$ of Belle II data, using events where the partner $B$-meson is reconstructed from a large variety of hadronic channels via a tagging algorithm known as the full-event-interpretation.

7. Reconstruction Methods for Semi-leptonic Decays of B-mesons with the Belle II Experiment / Nadia Toutounji ; Kevin Varvell [BELLE2-MTHESIS-2019-002] Presented on 21 01 2019 MSc
2019
The University of Sydney / Sydney
The Belle II detector located in Tsukuba, Japan, building on the work of its predecessor Belle, is scheduled for long-term data collection from electron-positron $e^{+} e^{-}$ collisions commencing in early 2019, for the purpose of studying rare B-meson decays in the search for new physics beyond the Standard Model.
