Search for the lepton flavour violating decays $B^{+} \to K^{+} τ^{\pm} ℓ^{\mp}$ ( $ℓ = e, μ$ ) at Belle

Belle Collaboration, S. Watanuki, G. de Marino +176

We present a search for the lepton-flavour-violating decays $B^{+} \to K^{+} τ^{\pm} ℓ^{\mp}$ , with $ℓ = (e, μ)$ , using the full data sample of $772 \times 1 0^{6}$ $B B$ pair…

Search for a heavy neutrino in $τ$ decays at Belle

Belle Collaboration, D. Liventsev, I. Adachi +189

We report on a search for a heavy neutrino in the decays $τ^{-} \to π^{-} ν_{h}$ , $ν_{h} \to π^{\pm} ℓ - +$ , $ℓ = e, μ$ . The results are obtained using the full data sample collected wit…

Determination of $∣ V_{u b} ∣$ from untagged $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ decays using 2019-2021 Belle II data

Belle II Collaboration, K. Adamczyk, L. Aggarwal +588

We present an analysis of the charmless semileptonic decay $B^{0} \to π^{-} ℓ^{+} ν_{ℓ}$ , where $ℓ = e, μ$ , from 198.0 million pairs of $B B ˉ$ mesons recorded by the Belle II…

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…

Measurement of branching fractions of $Λ_{c}^{+} \to p K_{S}^{0} K_{S}^{0}$ and $Λ_{c}^{+} \to p K_{S}^{0} η$ at Belle

Belle Collaboration, L. K. Li, K. Kinoshita +204

We present a study of a singly Cabibbo-suppressed decay $Λ_{c}^{+} \to p K_{S}^{0} K_{S}^{0}$ and a Cabibbo-favored decay $Λ_{c}^{+} \to p K_{S}^{0} η$ based on 980 $f b^{- 1}$ of data collected by the…

Evidence for the singly Cabibbo-suppressed decay $Ω_{c}^{0} \to Ξ^{-} π^{+}$ and search for $Ω_{c}^{0} \to Ξ^{-} K^{+}$ and $Ω^{-} K^{+}$ decays at Belle

Belle Collaboration, X. Han, S. Jia +170

Using a data sample of 980 fb $^{- 1}$ collected with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we study for the first time the singly Cabibbo-suppressed de…
