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…

Search for $C P$ violation and measurement of branching fractions and decay asymmetry parameters for $Λ_{c}^{+} \to Λ h^{+}$ and $Λ_{c}^{+} \to Σ^{0} h^{+}$ ( $h = K, π$ )

Belle Collaboration, L. K. Li, W. Shan +187

We report a study of $Λ_{c}^{+} \to Λ h^{+}$ and $Λ_{c}^{+} \to Σ^{0} h^{+}$ ( $h = K, π$ ) decays based on a data sample of 980~ $fb^{- 1}$ collected with the Belle detector at the KEKB energ…

Observation of $Ω (2012)^{-} \to Ξ (1530) K ˉ$ and measurement of the effective couplings of $Ω (2012)^{-}$ to $Ξ (1530) K ˉ$ and $Ξ K ˉ$

Belle Collaboration, S. Jia, C. P. Shen +117

Using $Υ (1 S)$ , $Υ (2 S)$ , and $Υ (3 S)$ data collected by the Belle detector, we discover a new three-body decay, $Ω (2012)^{-} \to Ξ (1530) K ˉ \to Ξ π K ˉ$ , with a significance of 5.2~ $σ$ …
