Constraining $|V_{cs}|$ and physics beyond the Standard Model from exclusive (semi)leptonic charm decays

Carolina Bolognani, Méril Reboud, Danny van Dyk +1

We study the available data on exclusive leptonic and semileptonic $c\to s{\ell }^{+}\nu$ decays within the Standard Model and beyond. Our analysis accounts for theory correlations betwee…
