13. Search for Wrong-Sign D0 → K+π−π0 decay at Belle II / Chanchal Sharma [BELLE2-CONF-PROC-2023-024]
12 July 2023

In the standard model, mixing and CP violation in the charm sector are expected to be very small, and thus, they constitute a sensitive probe for potential new physics contributions. [...]

18. Recent Belle II results on hadronic B decays / Sebastiano Raiz [BELLE2-CONF-PROC-2023-018]
04 July 2023

We report on recent measurements of $B$ meson decays to hadronic final states using electron-positron collisions at the $\Upsilon(4S)$ resonance collected from 2019 to 2022 by the Belle~II experiment and corresponding to an integrated luminosity of 362 ${\rm fb^{-1}}$. [...]
19. Status and prospects for rare B decays at Belle and Belle II / Gaetano de Marino [BELLE2-CONF-PROC-2023-017]

Rare $B$ decays are at the front of Belle~II physics program [...]
20. Studies on $\tau$ decays at Belle II / Laura Zani [BELLE2-CONF-PROC-2023-016]
03 July 2023

Tau leptons offer a very clean environment to study the process of hadronization and are powerful tools to probe physics beyond the Standard Model (SM), which might be enhanced due to mass-dependent couplings. [...]
