A study of gamma gamma -> Ks Ks production at energies of 2.4-4.0GeV at Belle

W. T. Chen

$K_{S}^{0} K_{S}^{0}$ production in two-photon collisions has been studied using a 397.6 fb $^{- 1}$ data sample collected with the Belle detector at the KEKB $e^{+} e^{-}$ collider. For the first…

Evidence of the Purely Leptonic Decay B- --> tau- nu_tau-bar

K. Ikado

We present the first evidence of the decay B- --> tau- nu_tau-bar using 414 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-ener…

Improved Measurement of the Electroweak Penguin Process B->Xsll

The Belle Collaboration, M. Iwasaki

We present an improved measurement of the branching fraction for the electroweak penguin process B->Xsll, where l is an electron or a muon and Xs is a hadronic system containing an…

Observation of $B^{0} \to D^{+} D^{-}$ , $B^{-} \to D^{0} D^{-}$ and $B^{-} \to D^{0} D^{*-}$ decays

G. Majumder

We report the first observation of the decay modes $B^{0} \to D^{+} D^{-}$ , $B^{-} \to D^{0} D^{-}$ and $B^{-} \to D^{0} D^{*-}$ based on 152 $\times$ 10 $^{6}$ $B B ˉ$ events collected at KEKB. T…

Observation of B0->pi0pi0

Y. Chao

We report the first observation of the decay B0->pi0pi0, using a 253/fb data sample collected at the Upsilon(4S) resonance with the Belle detector at the KEKB e+e- collider. The me…

Measurement of the e+e- -> D()+D()- cross-sections

T. Uglov

We report first measurements of e+e- -> D(*)+D(*)- processes far above threshold. The cross-sections for e+e- -> DT*+DL*- and e+e- -> D+D*T- at sqrt{s}=10.58 GeV/c2 are measured to…
