A test of lepton flavor universality with a measurement of $R(D^{*})$ using hadronic $B$ tagging at the Belle~II experiment / The Belle II Collaboration [BELLE2-NOTE-PH-2022-032] [BELLE2-PUB-DRAFT-2023-015] [BELLE2-PUB-PH-2024-001]

The ratio of branching fractions $R(D^{*}) = \mathcal{B}(\overline{B} \rightarrow D^{*} \tau^{-} \overline{\nu}_{\tau})$/$\mathcal{B} (\overline{B} \rightarrow D^{*} \ell^{-} \overline{\nu}_{\ell})$, where $\ell$ is an electron or muon, is measured using a Belle~II data sample with an integrated luminosity of $189~\mathrm{fb}^{-1}$ at the SuperKEKB asymmetric-energy $e^{+} e^{-}$ collider.

Measurements of Branching Fraction and time-dependent {\boldmath $C\!P$} Asymmetry in {\boldmath $\Bz\rightarrow \KS\piz$} Decays at Belle~II / S. Hazra ; A. B. Kaliyar ; G. B. Mohanty [BELLE2-PUB-PH-2023-001]
16 January 2023

We report the measurements of branching fraction ($\mathcal{B}$) and time dependent $\CP$-violating asymmetry ($\ACP$ and $\SCP$) in the charmless decays $\Bz\to K^0\pi^0$ at Belle~II. [...]

Measurement of the $\Omega_c^0$ lifetime at Belle II / Angelo Di Canto ; Nisar Nellikunnummel [BELLE2-PUB-PH-2022-001]
23 June 2022

We report on a measurement of the \Omgc lifetime using $\Omgc\to\Omg\pip$ decays reconstructed in the \epem-collision data collected by Belle~II between 2019 and the first half of 2021, which correspond to \lumi of integrated luminosity. [...]
