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…

Search for double charmonium decays of the P-wave spin-triplet bottomonium states

The Belle Collaboration

Using a sample of 158 million $Υ (2 S)$ events collected with the Belle detector, we search for the first time for double charmonium decays of the $P$ -wave spin-triplet bottomonium s…

Observation of two charged bottomonium-like resonances in Y(5S) decays

the Belle Collaboration

We report the observation of two narrow structures in the mass spectra of the pi+-Y(nS) (n=1,2,3) and pi+-hb(mP)(m$ (m=1,2) pairs that are produced in association with a single cha…

Search for the X(1812) in $B^{\pm} \to K^{\pm} ω ϕ$

The Belle Collaboration, C. Liu, Z. P. Zhang

We report on a search for the X(1812) state in the decay $B^{\pm} \to K^{\pm} ω ϕ$ with a data sample of $657 \times 1 0^{6}$ $B B ˉ$ pairs collected with the Belle detector at the KE…

Measurement of the e+e- -> J/psi ccbar cross section at \sqrt{s} ~10.6 GeV

P. Pakhlov

We present a new measurement of the e+e- -> J/psi ccbar cross section where the ccbar pair can fragment either into charmed hadrons or a charmonium state. In the former case the J/…

Improved measurement of CP-violating parameters in rho+rho- decays

A. Somov, A. J. Schwartz

We present a measurement of the CP-violating asymmetry in rho+rho- decays using 535 million BBbar pairs collected with the Belle detector at the KEKB e+e- collider. We measure CP-v…
