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…

First Observation of $Λ π^{+}$ and $Λ π^{-}$ Signals near the $K ˉ N (I = 1)$ Mass Threshold in $Λ_{c}^{+} \to Λ π^{+} π^{+} π^{-}$ Decay

Belle Collaboration, Y. Ma, J. Yelton +195

Using the data sample of 980 fb $^{- 1}$ collected with the Belle detector operating at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we present the results of an investigation of th…

Study of $e^{+} e^{-} \to Σ^{0} Σ^{0}$ and $Σ^{+} Σ^{-}$ by Initial State Radiation Method at Belle

Belle Collaboration, G. Gong, L. K. Li +195

The processes $e^{+} e^{-} \to Σ^{0} Σ^{0}$ and $e^{+} e^{-} \to Σ^{+} Σ^{-}$ are studied using initial-state-radiation events in a sample of 980 $\,\mbox{fb}^{-1…

Measurement of decay-time dependent $C P$ violation in $B^{0} \to K_{S}^{0} K_{S}^{0} K_{S}^{0}$ using 2019--2021 Belle II data

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

We report a measurement of decay-time dependent $C P$ -violating parameters in $B^{0} \to K_{S}^{0} K_{S}^{0} K_{S}^{0}$ decays. We use $(198.0 \pm 3.0) \times 1 0^{6} B B$ pairs c…

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…

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…
