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…

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…

Observation of B0bar --> D0 K0bar and B0bar --> D0 K*0bar decays

P. Krokovny

We report on a search for B0bar --> D0 K(*)0bar decays based on 85 10^6 BBar events collected with the Belle detector at KEKB. The B0bar --> D0 K0bar and B0bar --> D0 K*0bar decays…

Observation of B0bar->Lambda_c+pbar decay

N. Gabyshev, H. Kichimi

We report the measurement of the charmed baryonic decay B0bar->Lambda_c+pbar with a branching fraction of (2.19^{+0.56}_{-0.49}+-0.32+-0.57)x10^{-5} and a statistical significance…

Observation of

K. Abe, The Belle Collaboration

We report the first observation of the decay using 21.3 fb of data collected by the Belle detector at the (4S) resonance. The preliminary result for…
