Measurements of the Branching Fractions $B (B^{-} \to Λ ˉ_{c}^{-} Ξ_{c}^{^{'} 0})$ , $B (B^{-} \to Λ ˉ_{c}^{-} Ξ_{c} (2645)^{0})$ and $B (B^{-} \to Λ ˉ_{c}^{-} Ξ_{c} (2790)^{0})$

Belle Collaboration, Y. Li, Y. B. Li +173

Using the data sample of 711 fb $^{- 1}$ of $Υ (4 S)$ on-resonance data taken by the Belle detector at the KEKB asymmetric-energy electron-positron collider, we present the first measu…

Observation of a vector charmoniumlike state in $e^{+} e^{-} \to D_{s}^{+} D_{s 1} (2536)^{-} + c . c .$

Belle Collaboration, S. Jia, C. P. Shen +171

Using a data sample of 921.9 fb $^{- 1}$ collected with the Belle detector, we study the process of $e^{+} e^{-} \to D_{s}^{+} D_{s 1} (2536)^{-} + c . c .$ via initial-state radiation. We report the fi…

Observation of the radiative decays of $Υ (1 S)$ to $χ_{c 1}$

P. Katrenko, I. Adachi, H. Aihara +166

We report the first observation of the radiative decay of the $Υ (1 S)$ into a charmonium state. The statistical significance of the observed signal of $Υ (1 S) \to γ χ_{c 1}$ is 6.3 sta…

Measurement of the integrated luminosity of the Phase 2 data of the Belle II experiment

Belle II Collaboration, F. Abudinén, I. Adachi +420

From April to July 2018, a data sample at the peak energy of the $Υ (4 S)$ resonance was collected with the Belle~II detector at the SuperKEKB electron-positron collider. This is the…

Azimuthal asymmetries of back-to-back $π^{\pm} - (π^{0}, η, π^{\pm})$ pairs in $e^{+} e^{-}$ annihilation

Belle Collaboration, H. Li, A. Vossen +126

This work reports the first observation of azimuthal asymmetries around the thrust axis in $e^{+} e^{-}$ annihilation of pairs of back-to-back charged pions in one hemisphere, and $π^{0}$ …

First measurement of the CKM angle $ϕ_{3}$ with $B^{\pm} \to D (K_{S}^{0} π^{+} π^{-} π^{0}) K^{\pm}$ decays

Belle Collaboration, P. K. Resmi, J. Libby +165

We present the first model-independent measurement of the CKM unitarity triangle angle $ϕ_{3}$ using $B^{\pm} \to D (K_{S}^{0} π^{+} π^{-} π^{0}) K^{\pm}$ decays, where $D$ indicates either a…
