Measurement of B -> D^(*) tau nu using full reconstruction tags

I. Adachi

We present measurements of B -> D^* tau nu and B -> D tau nu decays using 604.5 fb^-1 of data collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asymmetric-…

First Measurement of Inclusive B -> X_s eta Decays

Belle Collaboration, K. Nishimura, T. E. Browder +140

We report a first measurement of inclusive B -> X_s eta decays, where X_s is a charmless state with unit strangeness. The measurement is based on a pseudo-inclusive reconstruction…

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…
