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
A. Ishikawa
We report the first observation of the flavor-changing neutral current decay and an improved measurement of the decay , where $\ell…
Observation of radiative B -> phi K gamma decays
A. Drutskoy
The radiative decay is observed for the first time. The branching fraction for the charged decay mode is measured to be ${\cal B}(B^- \to ϕK^- γ) = (3…
Measurement of the CP Asymmetry in B -> X_s gamma
S. Nishida
Direct CP violation in the b->sgamma process is a sensitive probe of physics beyond the Standard Model. We report a measurement of the CP asymmetry in B -> X_s gamma, where the had…
Observation of B+ -> rho+ rho0
J. Zhang, M. Nakao
We report the first observation of the charmless vector-vector decay process B+ ->rho+ rho0. The measurement uses a 78 fb^{-1} data sample collected with the Belle detector at the…
Observation of B -> phi phi K
H. -C. Huang
We report the observation of the decay mode B -> phi phi K based on an analysis of 78 fb^{-1} of data collected with the Belle detector at KEKB. This is the first example of a b ->…
Observation of B0 to p Lambdabar pi-
M. -Z. Wang
We report the first observation of the charmless hyperonic B decay, B0 -> p Lambdabar pi-, using a 78 fb^-1 data sample recorded on the Upsilon(4S) resonance with the Belle detecto…
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…
