000000577 520__ $$aSemileptonic B meson decays involving low-mass charged leptons e or µ are expected to be free of non-Standard Model contributions and therefore play a critical role in determinations of |Vub| and |Vcb|. Of all the CKM matrix parameters, |Vub| is the least precisely measured and in most need of additional studies in order to better constrain the apex of the Unitarity Triangle. We focus on exclusive reconstruction of charmless semileptonic B meson decay B -> πlν, and present prospects and estimates for measuring |Vub| at Belle II with the full planned dataset of 50 ab−1 of integrated luminosity.
