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 $\vert V_{cb} \vert$. [...]
