A search for feebly-interacting particles in $B$ decays with missing energy at Belle

Belle, Belle II Collaborations, : +406

We present a search for an invisible hidden-sector particle $X_{inv}$ , produced in $B^{0} \to D ˉ^{0} X_{inv}$ and $B^{\pm} \to h X_{inv}$ decays, where $h = π^{\pm}$ , $…

Search for $B^{0} \to K^{* 0} τ^{+} τ^{-}$ decays at the Belle II experiment

Belle II Collaboration, I. Adachi, K. Adamczyk +446

We present a search for the rare flavor-changing neutral-current decay $B^{0} \to K^{* 0} τ^{+} τ^{-}$ with data collected by the Belle II experiment at the SuperKEKB electron-positro…

Measurement of $B^{+} \to τ^{+} ν_{τ}$ branching fraction with a hadronic tagging method at Belle II

Belle II Collaboration, I. Adachi, K. Adamczyk +341

We present a measurement of the branching fraction of $B^{+} \to τ^{+} ν_{τ}$ decays using $(387 \pm 6) \times 1 0^{6}$ $Υ (4 S)$ collected between 2019 and 2022 with the Belle II detector at the S…
