We report an update to our previous measurement of the CKM element $|V_{ub}|$ using exclusive $B \rightarrow \pi \ell \nu$ decays. In the charm sector we have performed a measurement of $f_{Ds}$ using $D_s\rightarrow\tau^+\nu_{\tau}$…

In this decade, there are huge efforts to explore B-meson decays, which provide an interesting playground for stringent tests of the Standard-Model description of the quark-flavour sector and the CP violation residing there. Thanks to the…

In this talk we report on a study on the mixing of neutral charmed mesons and argue that, at the present stage, a CP violating weak phase of the order of some per mille can not be excluded in the Standard Model. It is shown how some,…

$\Dz-\Dzb$ mixing and significant CP violation in the charm system may indicate the signature of new physics. In this study, we suggest that the coherent $\DzDzb$ events from the decay of $\Upsilon(1S) \to \Dz \Dzb$ can be used to measure…
