Search for lepton-flavor-violating $τ^{-} \to ℓ^{-} ϕ$ decays in 2019-2021 Belle II data

Belle II Collaboration, F. Abudinén, I. Adachi +575

We report a search for lepton-flavor-violating decays $τ^{-} \to ℓ^{-} ϕ$ ( $ℓ^{-} = e^{-}, μ^{-}$ ) at the Belle II experiment, using a sample of electron-positron data produced at the Su…

Search for the Decay $B_{s}^{0} \to η^{'} η$

Belle Collaboration, A. Abdesselam, I. Adachi +459

In the Standard Model (SM) charmless hadronic decays $B_{s}^{0} \to η^{'} η$ proceed via tree-level $b \to u$ and penguin $b \to s$ transitions. Penguin transitions are sensit…
