CP violation and mixing in the charm sector at Belle, and current HFAG averages

B. R. Ko

Current HFAG averages of the mixing and CP violation parameters in the $D^{0}$ meson system is to be reviewed. We present recent Belle measurements of the mixing parameters $x$ and $…

Direct CP violation in charm at Belle

B. R. Ko

Using the full data sample collected with the Belle detector at the KEKB asymmetric-energy $e^{+} e^{-}$ collider, we have searched for CP violation of charmed mesons in $D^+\rightarrow…

Study of the Hadronic Transitions $Υ$ (2S) $\to (η, π^{0}) Υ$ (1S) at Belle

Belle Collaboration, U. Tamponi, R. Mussa +131

We study the rare hadronic transitions $Υ (2 S) \to Υ (1 S) η$ and $Υ (2 S) \to Υ (1 S) π^{0}$ using a sample of 158 $\times 1 0^{6}$ $Υ (2 S)$ decays collected with the Belle detecto…

Precise measurement of the branching fractions for Bs->Ds()+ Ds()- and first measurement of the Ds+ Ds- polarization using e+e- collisions

S. Esen, A. J. Schwartz, H. Aihara +137

We have made a precise measurement of the absolute branching fractions of Bs->Ds(*)+ Ds(*)- decays using 121.4 fb-1 of data recorded by the Belle experiment running on the Upsilon(…

Evidence for a Zb0(10610) in Dalitz analysis of Y(5S) -> Y(nS) pi0 pi0

I. Adachi, K. Adamczyk, H. Aihara +331

We report the first observation of Y(5S) -> Y(1,2S) pi0 pi0 decays. Evidence for the Zb0(10610) with 4.9sigma significance is found in a Dalitz plot analysis of Y(5S) -> Y(2S) pi0…
