Search for the lepton flavour violating decays $B^{+} \to K^{+} τ^{\pm} ℓ^{\mp}$ ( $ℓ = e, μ$ ) at Belle

Belle Collaboration, S. Watanuki, G. de Marino +176

We present a search for the lepton-flavour-violating decays $B^{+} \to K^{+} τ^{\pm} ℓ^{\mp}$ , with $ℓ = (e, μ)$ , using the full data sample of $772 \times 1 0^{6}$ $B B$ pair…

Search for an invisible $Z^{'}$ in a final state with two muons and missing energy at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +385

The $L_{μ} - L_{τ}$ extension of the standard model predicts the existence of a lepton-flavor-universality-violating $Z^{'}$ boson that couples only to the heavier lepton families.…

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…

Measurement of branching fractions of $Λ_{c}^{+} \to p K_{S}^{0} K_{S}^{0}$ and $Λ_{c}^{+} \to p K_{S}^{0} η$ at Belle

Belle Collaboration, L. K. Li, K. Kinoshita +204

We present a study of a singly Cabibbo-suppressed decay $Λ_{c}^{+} \to p K_{S}^{0} K_{S}^{0}$ and a Cabibbo-favored decay $Λ_{c}^{+} \to p K_{S}^{0} η$ based on 980 $f b^{- 1}$ of data collected by the…
