Observation of B+ to p Lambdabar pi+ pi- at Belle

P. Chen, M. -Z. Wang

We study charmless $B^{+}$ meson decays to the $p Λ ˉ π^{+} π^{-}$ final state using a $605 fb^{- 1}$ data sample collected at the $Υ (4 S)$ resonance with the Belle detector at the…

Measurement of $D^{+} \to K_{S}^{0} K^{+}$ and $D_{s}^{+} \to K_{S}^{0} π^{+}$ branching ratios

E. Won, B. R. Ko

We report an improved measurement of $D^{+} \to K_{S}^{0} K^{+}$ and $D_{s}^{+} \to K_{S}^{0} π^{+}$ branching ratios using 605 fb $^{- 1}$ of data collected with the Belle detector at the KEKB asymmet…

Search for Lepton Flavor and Lepton Number Violating tau Decays into a Lepton and Two Charged Mesons

Y. Miyazaki

We search for lepton flavor and lepton number violating tau decays into a lepton (ell = electron or muon) and two charged mesons (h,h' = pi^\pm or K^\pm), tau- -> ell-h+h'- and tau…

Measurement of the e+e- --> D0D*-pi+ cross section using initial-state radiation

Belle Collaboration, G. Pakhlova

We report measurements of the exclusive cross section for e+e- --> D0D*-pi+ as function of center-of-mass energy from the D0D*-pi+ threshold to 5.2 GeV with initial-state radiation…

High-statistics study of ${\boldmath ηπ^0}$ production in two-photon collisions

S. Uehara

The differential cross section for the process $γ γ \to η π^{0}$ has been measured in the kinematic range $0.84 \GeV < W < 4.0 \GeV$, $∣ cos θ^{*} ∣ < 0.8$ , where $W$ and $θ^{*}$ are the energ…

Measurement of $y_{C P}$ in $D^{0}$ meson decays to the $K_{S}^{0} K^{+} K^{-}$ final state

The Belle Collaboration

We present a measurement of the $D^{0}$ - $D^{0}$ mixing parameter $y_{C P}$ using a flavor-untagged sample of $D^{0} \to K_{S}^{0} K^{+} K^{-}$ decays. The measurement is based on a 673…

Dalitz analysis of B --> K pi psi' decays and the Z(4430)+

R. Mizuk

From a Dalitz plot analysis of B --> K pi psi' decays, we find a signal for Z(4430)+ --> pi+ psi' with a mass M= (4443(+15-12)(+19-13))MeV/c^2, width Gamma= (107(+86-43)(+74-56))Me…

Measurement of the Differential Branching Fraction and Forward-Backword Asymmetry for B->K(*)l+l-

J. -T. Wei, P. Chang

We study B->K(*)l+l- decays (l=e,mu) based on a data sample of 657 million BB pairs collected with the Belle detector at the KEKB e+e- collider. We report the differential branchin…
