1. Measurement of the branching fraction of $B^{0}\to D^{*-}l^{+}\nu_{l}$ with early Belle II data / Minakshi Nayak ; Abner Soffer ; Florian Bernlochner ; Lu Cao ; et al [BELLE2-CONF-PH-2020-002]
15 April 2020

We measure the branching fractions for the decays $B^{0}\to D^{*-}e^{+}\nu_{e}$ and $B^{*0}\to D^{*-}\mu^{+}\nu_{\mu}$ using the first $8.70 \pm 0.09 fb^{-}$ of data collected by the Belle II experiment at the SuperKEKB asymmetric-energy $e^+ e^-$ collider using the decays $D^{*+}\to D^0 \pi^+$ and $D^0\to K^-\pi^+$..

6. Determination of Vub at Belle II / Matic Lubej [BELLE2-TALK-DRAFT-2017-008] [BELLE2-TALK-CONF-2017-040] 5' (3'+2') 9 actual slides + many backup slides
24 March 2017
/ Moriond EW 2017
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 $\vert V_{cb} \vert$. [...]
