Measurement of branching fractions and $C P$ asymmetries for $D_{s}^{+} \to K^{+} (η, π^{0})$ and $D_{s}^{+} \to π^{+} (η, π^{0})$ decays at Belle

Belle Collaboration, Y. Guan, A. J. Schwartz +200

We report measurements of the branching fractions and $C P$ asymmetries for $D_{s}^{+} \to K^{+} η$ , $D_{s}^{+} \to K^{+} π^{0}$ , and $D_{s}^{+} \to π^{+} η$ decays…

First observation of the P-wave spin-singlet bottomonium states h_b(1P) and h_b(2P)

Belle Collaboration

We report the first observation of the spin-singlet bottomonium states h_b(1P) and h_b(2P) produced in the reaction e+e- --> hb(nP)pi+pi- using a 121.4fb-1 data sample collected at…

Observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and Evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$

Jin Li

We report the first observation of $B_{s}^{0} \to J / ψ f_{0} (980)$ and first evidence for $B_{s}^{0} \to J / ψ f_{0} (1370)$ , which are CP eigenstate decay modes. These results are obtained from $121.…

Search for CP Violation in the Decays $D^{0} \to K_{S}^{0} P^{0}$

B. R. Ko, E. Won

We have searched for CP violation in the decays $D^{0} \to K_{S}^{0} P^{0}$ where $P^{0}$ denotes a neutral pseudo-scalar meson which is either a $π^{0}$ , $η$ , or $η^{'}$ using KEKB asymme…

Search for CP violating charge asymmetry in B^+ -> J/psi K^+ decays

K. Sakai, T. Kawasaki, H. Aihara +136

We present the result of a search for charge asymmetry in B^+ -> J/psi K^+ decays. The CP-violating charge asymmetry is measured to be A_CP(B^+ -> J/psi K^+) = [-0.76 +/- 0.50 (sta…
