/ Lepton Photon 2023
Semileptonic $B$-meson decays allow for determining the magnitudes of the CKM matrix parameters $|V_{cb}|$ and $|V_{ub}|$, two fundamental parameters of the SM flavor sector and to probe the excess rate of semitauonic $B$ decays, which has been consistently above expectations in recent years. [...]

12 July 2023

Recent measurements of semileptonic decays show a difference between the branching ratio of the sum of exclusive decay rates and the inclusive $b \rightarrow c \ell \nu$ decay rate (the so-called Semi-Leptonic (SL) gap) which affects the interpretation of the CKM element $|Vcb|$. [...]
