Determination of $∣ V_{c b} ∣$ from $B \to D ℓ ν$ decays using 2019-2021 Belle II data

Belle II collaboration, F. Abudinén, I. Adachi +590

We present a determination of the magnitude of the Cabibbo-Kobayashi-Maskawa (CKM) matrix element $V_{c b}$ using $B \to D ℓ ν$ decays. The result is based on $e^{+} e^{-} \to Υ (4 S)$ data…

Measurement of the photon-energy spectrum in inclusive $B \to X_{s} γ$ decays identified using hadronic decays of the recoil $B$ meson in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +593

We measure the photon-energy spectrum in radiative bottom-meson ( $B$ ) decays into inclusive final states involving a strange hadron and a photon. We use SuperKEKB electron-positron…
