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…

First observation of $B \to D ˉ_{1} (\to D ˉ π^{+} π^{-}) ℓ^{+} ν_{ℓ}$ and measurement of the $B \to D ˉ^{()} π ℓ^{+} ν_{ℓ}$ and $B \to D ˉ^{()} π^{+} π^{-} ℓ^{+} ν_{ℓ}$ branching fractions with hadronic tagging at Belle

Belle Collaboration, F. Meier, A. Vossen +202

We report measurements of the ratios of branching fractions for $B \to D ˉ^{(*)} π ℓ^{+} ν_{ℓ}$ and $B \to D ˉ^{(*)} π^{+} π^{-} ℓ^{+} ν_{ℓ}$ relative to $B \to \bar{D}^*\ell^+ν_\…

Search for a heavy neutrino in $τ$ decays at Belle

Belle Collaboration, D. Liventsev, I. Adachi +189

We report on a search for a heavy neutrino in the decays $τ^{-} \to π^{-} ν_{h}$ , $ν_{h} \to π^{\pm} ℓ - +$ , $ℓ = e, μ$ . The results are obtained using the full data sample collected wit…

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.…

Reconstruction of $B \to ρ ℓ ν_{ℓ}$ decays identified using hadronic decays of the recoil $B$ meson in 2019 -- 2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +580

We present results on the semileptonic decays $B^{0} \to ρ^{-} ℓ^{+} ν_{ℓ}$ and $B^{+} \to ρ^{0} ℓ^{+} ν_{ℓ}$ in a sample corresponding to 189.9/fb of Belle II data at the SuperKEKB $e…

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…
