Search for light tetraquark states in $Υ (1 S)$ and $Υ (2 S)$ decays

Belle Collaboration, S. Jia, C. P. Shen +192

We search for the $J^{P C} = 0^{--}$ and $1^{+-}$ light tetraquark states with masses up to 2.46~GeV/ $c^{2}$ in $Υ (1 S)$ and $Υ (2 S)$ decays with data samples of $(102 \pm 2)$ million and…

Observation of $Ξ_{c} (2930)^{0}$ and updated measurement of $B^{-} \to K^{-} Λ_{c}^{+} Λ ˉ_{c}^{-}$ at Belle

Belle Collaboration, Y. B. Li, C. P. Shen +178

We report the first observation of the $Ξ_{c} (2930)^{0}$ charmed-strange baryon with a significance greater than 5 $σ$ . The $Ξ_{c} (2930)^{0}$ is found in its decay to $K^{-} Λ_{c}^{+}$ in $…

Observation of Excited $Ω_{c}$ Charmed Baryons in $e^{+} e^{-}$ Collisions

Belle Collaboration, J. Yelton, I. Adachi +177

Using the entire Belle data sample of 980 $fb^{- 1}$ of $e^{+} e^{-}$ collisions, we present the results of a study of excited $Ω_{c}$ charmed baryons in the decay mode $Ξ_{c}^{+} K^{-}$ . W…

Study of $η$ and dipion transitions in $Υ (4 S)$ decays to lower bottomonia

Belle Collaboration, E. Guido, R. Mussa +178

We study hadronic transitions between bottomonium states using 496 fb $^{- 1}$ data collected at the $Υ (4 S)$ resonance with the Belle detector at the KEKB asymmetric energy $e^{+}e^{…

Evidence for Isospin Violation and Measurement of $C P$ Asymmetries in $B \to K^{*} (892) γ$

T. Horiguchi, A. Ishikawa, H. Yamamoto +190

We report the first evidence for isospin violation in $B \to K^{*} γ$ and the first measurement of difference of $C P$ asymmetries between $B^{+} \to K^{*+} γ$ and $B^{0} \to K^{* 0} γ$ . T…

Invariant-mass and fractional-energy dependence of inclusive production of di-hadrons in $e^{+} e^{-}$ annihilation at $s =$ 10.58 GeV

Belle Collaboration, R. Seidl, I. Adachi +159

The inclusive cross sections for di-hadrons of charged pions and kaons ( $e^{+} e^{-} \to hh X$ ) in electron-positron annihilation are reported. They are obtained as a function of…
