First Measurement of the $Λ_{c}^{+} \to p η^{'}$ decay

Belle Collaboration, S. X. Li, J. X. Cui +197

We present the first measurement of the branching fraction of the singly Cabibbo-suppressed (SCS) decay $Λ_{c}^{+} \to p η^{'}$ with $η^{'} \to η π^{+} π^{-}$ , using a data sample corresponding to…

Exclusive $B \to X_{u} ℓ ν_{ℓ}$ Decays with Hadronic Full-event-interpretation Tagging in 62.8 fb $^{- 1}$ of Belle II Data

Belle II Collaboration, F. Abudinén, I. Adachi +565

We present a reconstruction in early data of the semileptonic decay $B^{+} \to π^{0} ℓ^{+} ν_{ℓ}$ , and first results of a reconstruction of the decays $B^{+} \to ρ^{0} ℓ^{+} ν_{ℓ}$ and…

Combined analysis of Belle and Belle II data to determine the CKM angle $ϕ_{3}$ using $B^{+} \to D (K_{S}^{0} h^{-} h^{+}) h^{+}$ decays

Belle, Belle II Collaborations, : +319

We present a measurement of the Cabibbo-Kobayashi-Maskawa unitarity triangle angle $ϕ_{3}$ (also known as~ $γ$ ) using a model-independent Dalitz plot analysis of \linebreak $B^+\t…

$B$ -flavor tagging at Belle II

F. Abudinén, N. Akopov, A. Aloisio +118

We report on new flavor tagging algorithms developed to determine the quark-flavor content of bottom ( $B$ ) mesons at Belle II. The algorithms provide essential inputs for measureme…

Study of $χ_{b J} (n P) \to ω Υ (1 S)$ at Belle

Belle Collaboration, A. Abdesselam, I. Adachi +470

We report results from a study of hadronic transitions of the $χ_{b J} (n P)$ states of bottomonium at Belle. The $P$ -wave states are reconstructed in transitions to the $Υ (1 S)$ with…

Search for $B^{0} \to τ^{\pm} ℓ^{\mp}$ ( $ℓ = e, μ$ ) with a hadronic tagging method at Belle

Belle Collaboration, H. Atmacan, A. J. Schwartz +219

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