Determination of $∣ V_{u b} ∣$ from untagged $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ decays using 2019-2021 Belle II data

Belle II Collaboration, K. Adamczyk, L. Aggarwal +588

We present an analysis of the charmless semileptonic decay $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ , where $ℓ = e, μ$ , from 198.0 million pairs of $B B ˉ$ mesons recorded by the Belle II…

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…

Measurements of the branching fraction, isospin asymmetry, and lepton-universality ratio in $B \to J / ψ K$ decays at Belle II

Belle II Collaboration, F. Abudinén, I. Adachi +591

We report a study of $B \to J / ψ (ℓ^{+} ℓ^{-}) K$ decays, where $ℓ$ represents an electron or a muon, using $e^{+} e^{-}$ collisions at the $Υ (4 S)$ resonance. The data were col…

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

We report on a Belle II measurement of the branching fraction ( $B$ ), longitudinal polarization fraction ( $f_{L}$ ), and CP asymmetry ( $A_{C P}$ ) of $B^{+} \to ρ^{+} ρ^{0}$ …
