Can the differences in the determinations of $V_{ub}$ and $V_{cb}$ be explained by New Physics?
The precise determination of the CKM elements $V_{cb}$ and $V_{ub}$ is crucial for any new physics analysis in the flavour sector. Their values can be determined from several tree-level decays: $V_{cb}$ can be extracted from $B\to D\ell\nu$ and $B\to D^*\ell\nu$ while $V_{ub}$ can be obtained from $...
