/ FTCF 2024
In this talk, I present some recent charm results at Belle and Belle II experiments, including the precise measurement of charm lifetimes, branching fractions and decay asymmetry parameter, searches for rare and forbidden decays (Xic semileptonic decay, BNV processes D->p l), and CPV searches for charm hadron decays (D four-body decays and Lambda_c singly Cabibbo-suppressed decays)..

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.

$D^{0}\longrightarrow K^{0}_{s}K^{0}_{s}$ is a Singly Cabibbo Suppressed decay, which involves the interference of $c\overline{u}\longrightarrow s\overline{s}$ and $c\overline{u}\longrightarrow d\overline{d}$ transitions. [...]

/ Chanchal Sharma, Kavita Lalwani
[BELLE2-CONF-PROC-2023-047]
27 December 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. [...]
