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 Lepton-Flavor-Violating $τ$ Decays to a Lepton and an Invisible Boson at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +398

We search for lepton-flavor-violating $τ^{-} \to e^{-} α$ and $τ^{-} \to μ^{-} α$ decays, where $α$ is an invisible spin-0 boson. The search uses electron-positron collisions at $10.58$ GeV cen…

Measurement of the branching fraction and search for $C P$ violation in $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ decays at Belle

Aman Sangal

We measure the branching fraction for the Singly Cabibbo-suppressed decay $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ , and we search for $C P$ violation via a measurement of the $C P$ asym…

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…

Measurement of the branching fraction and search for CP violation in $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ decays at Belle

The Belle Collaboration

We measure the branching fraction for the Cabibbo-suppressed decay $D^{0} \to K_{S}^{0} K_{S}^{0} π^{+} π^{-}$ and search for $C P$ violation via a measurement of the $C P$ asymmetry $A_{\…

Angular analysis of $B^{+} \to ρ^{+} ρ^{0}$ decays reconstructed in 2019, 2020, and 2021 Belle II data

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 $B^{+} \to ρ^{+} ρ^{0}$ …
