Determination of $|V_{ub}|$ from untagged $B^0\toπ^- \ell^+ ν_{\ell}$ decays using 2019-2021 Belle II data

Belle II Collaboration, K. Adamczyk, L. Aggarwal, P. Ahlburg et autres

We present an analysis of the charmless semileptonic decay $B^0\toπ^- \ell^+ ν_{\ell}$, where $\ell = e, μ$, from 198.0 million pairs of $B\bar{B}$ mesons recorded by the Belle II detector at the SuperKEKB electron-positron collider. The decay is reconstructed without identifying the …

Measurement of Differential Branching Fractions of Inclusive ${B \to X_u \, \ell^+\, \nu_{\ell}}$ Decays

L. Cao, William L. Sutcliffe, Raynette van Tonder, F. U. Bernlochner et autres

The first measurements of differential branching fractions of inclusive semileptonic ${B \to X_u \, \ell^+\, \nu_{\ell}}$ decays are performed using the full Belle data set of 711 fb$^{-1}$ of integrated luminosity at the $ϒ(4S)$ resonance and for $ℓ=e, μ$. With the availability …
