Observation of a narrow charmonium-like state in exclusive B+ -> K+ pi+pi- J/psi decays

The Belle Collaboration, S. -K. Choi, S. L. Olsen

We report the observation of a narrow charmonium-like state produced in the exclusive decay process B+ -> K+ pi+pi- J/psi. This state, which decays into pi+pi- J/psi, has a mass of…

Observation of $B \to K^{*} ℓ^{+} ℓ^{-}$

A. Ishikawa

We report the first observation of the flavor-changing neutral current decay $B \to K^{*} ℓ^{+} ℓ^{-}$ and an improved measurement of the decay $B \to K ℓ^{+} ℓ^{-}$ , where $\ell…

Measurement of Time-Dependent CP-Violating Asymmetries in B0 --> phi Ks0, K+ K- Ks0, and eta' Ks0 Decays

The Belle Collaboration, K. Abe

We present an improved measurement of CP-violation parameters in B0 --> phi Ks0, K+ K- Ks0, and eta' Ks0 decays based on a 140 fb-1 data sample collected at the Upsilon(4S) resonan…
