Precise determination of the magnitudes and phases of the elements, in particular, Vcb and Vub, of the Cabibbo-Kobayashi-Maskawa (CKM) matrix is crucial for testing the unitarity of the CKM matrix, hence testing the Standard Model. [...]

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. [...]

| Study of Exclusive $B \to \pi e^+ \nu_e$ Decays with Hadronic Full-event-interpretation Tagging in 189.3 fb$^{-1}$ of Belle II Data
/ Nadia Toutounji ; Moritz Bauer ; Pablo Goldenzweig ; Kevin Varvell
[BELLE2-CONF-PH-2022-008]
16 June 2022
We present a reconstruction of the semileptonic decays $B^0 \to \pi^- e^+ \nu_e$ and $B^+ \to \pi^0 e^+ \nu_e$ in a sample corresponding to 189.3 fb$^{-1}$ of Belle II data, using events where the partner $B$-meson is reconstructed from a large variety of hadronic channels via a tagging algorithm known as the full-event-interpretation.

| Determination of |Vub| at Belle II
/ Matic Lubej
[BELLE2-CONF-PROC-2017-023]
12 May 2017
Semileptonic B meson decays involving low-mass charged leptons e or ยต are expected to be free of non-Standard Model contributions and therefore play a critical role in determinations of |Vub| and |Vcb|. [...]

Semileptonic decays of $B$ mesons involving low-mass charged leptons $e$ or $\mu$ are expected to be free of non-Standard Model contributions and therefore play a critical role in determinations of $\vert V_{ub} \vert$ and $\vert V_{cb} \vert$. [...]
