Search for $B_{s}^{0} \to γ γ$ and a measurement of the branching fraction for $B_{s}^{0} \to ϕ γ$

Belle Collaboration, D. Dutta, B. Bhuyan +148

We search for the decay $B_{s}^{0} \to γ γ$ and measure the branching fraction for $B_{s}^{0} \to ϕ γ$ using 121.4~ $fb^{- 1}$ of data collected at the $Υ(\mathrm{…

Observation of $e^{+} e^{-} \to π^{+} π^{-} π^{0} χ_{b J}$ and search for $X_{b} \to ω Υ (1 S)$ at $s \sim 10.867$ GeV

Belle Collaboration, X. H. He, C. P. Shen +158

The $e^{+} e^{-} \to π^{+} π^{-} π^{0} χ_{b J}$ ( $J = 0, 1, 2$ ) processes are studied using a 118~fb $^{- 1}$ data sample collected at a center-of-mass energy of 10.867 GeV, in the $Υ (10860)$ ener…

Study of CP Violation in Flavor Tagged and Untagged $D^{0} \to K^{-} π^{+}$ Decays

E. Won, B. R. Ko, B. Golob

We review $C P$ -violating observables in flavor tagged and untagged $D^{0} \to K^{-} π^{+}$ decays and evaluate the $C P$ asymmetry difference between the two decays. We note th…

Evidence of $Υ (1 S) \to J / ψ + χ_{c 1}$ and search for double-charmonium production in $Υ (1 S)$ and $Υ (2 S)$ decays

Belle Collaboration, S. D. Yang, C. P. Shen +155

Using data samples of $102 \times 1 0^{6}$ $Υ (1 S)$ and $158 \times 1 0^{6}$ $Υ (2 S)$ events collected with the Belle detector, a first experimental search has been made for double-charmonium…

Observation of a new charged charmoniumlike state in B -> J/psi K pi decays

Belle Collaboration, K. Chilikin, R. Mizuk +162

We present the results of an amplitude analysis of anti-B0 -> J/psi K- pi+ decays. A new charged charmoniumlike state Zc(4200)+ decaying to J/psi pi+ is observed with a significanc…

Measurement of Time-Dependent $C P$ Violation in $B^{0} \to η^{'} K^{0}$ Decays

Belle Collaboration, L. Šantelj, Y. Yusa +163

We present a measurement of the time-dependent $C P$ violation parameters in $B^{0} \to η^{'} K^{0}$ decays. The measurement is based on the full data sample containing $772 \times 1 0^{6}$ $B\ba…
