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…

Measurement of the $τ$ lepton polarization and $R (D^{})$ in the decay $B ˉ \to D^{} τ^{-} ν ˉ_{τ}$ with one-prong hadronic $τ$ decays at Belle

S. Hirose, T. Iijima, I. Adachi +181

With the full data sample of $772 \times 1 0^{6}$ $B B ˉ$ pairs recorded by the Belle detector at the KEKB electron-positron collider, the decay $\bar{B} \rightarrow D^* τ^- \barν…

Angular analysis of the $e^{+} e^{-} \to D^{() \pm} D^{\mp}$ process near the open charm threshold using initial-state radiation

Belle Collaboration, V. Zhukova, H. Aihara +149

We report a new measurement of the exclusive $e^{+} e^{-} \to D^{(*) \pm} D^{*\mp}$ cross sections as a function of the center-of-mass energy from the $D^{(*) \pm} D^{*\mp}$ threshold…

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…

Search for $Λ_{c}^{+} \to ϕp π^{0}$ and branching fraction measurement of $Λ_{c}^{+} \to K^{-} π^{+} p π^{0}$

Belle Collaboration, B. Pal, A. J. Schwartz +154

We have searched for the Cabibbo-suppressed decay $Λ_{c}^{+} \to ϕp π^{0}$ in $e^{+} e^{-}$ collisions using a data sample corresponding to an integrated luminosity of 915 $f b^{- 1}$ . The dat…
