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 $Ω_{c}^{0}$ lifetime at Belle II

Belle II Collaboration, F. Abudinén, I. Adachi +353

We report on a measurement of the $Ω_{c}^{0}$ lifetime using $Ω_{c}^{0} \to Ω^{-} π^{+}$ decays reconstructed in $e^{+} e^{-} \to c c ˉ$ data collected by the Belle II experiment and corresponding…

Measurement of the branching fraction of the $B^{0} \to K_{S}^{0} π^{0} γ$ decay using 190 fb $^{- 1}$ of Belle II data

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

We report the measurement of the branching fraction of the $B^{0} \to K_{S}^{0} π^{0} γ$ decay in $e^{+} e^{-} \to Υ (4 S) \to B B$ data recorded by the Belle II experiment at the Sup…

Study of Exclusive $B \to π e^{+} ν_{e}$ Decays with Hadronic Full-event-interpretation Tagging in 189.3 fb $^{- 1}$ of Belle II Data

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

We present a reconstruction of the semileptonic decays $B^{0} \to π^{-} e^{+} ν_{e}$ and $B^{+} \to π^{0} e^{+} ν_{e}$ in a sample corresponding to 189.3 fb $^{- 1}$ of Belle II data, using events w…

Measurement of the branching fraction for the decay $B \to K^{*} (892) ℓ^{+} ℓ^{-}$ at Belle II

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

We report a measurement of the branching fraction of $B \to K^{*} (892) ℓ^{+} ℓ^{-}$ decays, where $ℓ^{+} ℓ^{-} = μ^{+} μ^{-}$ or $e^{+} e^{-}$ , using electron-positron collisions recorde…
