Pion Form Factor Phase, PIon Pion Elasticity and New Electron-Positron Data
S. Eidelman, L. Lukaszuk
New precise data on the low energy electron-positron annihilation into hadrons from Novosibirsk are used to obtain bounds on the elasticity parameter and the difference between the…
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…
An Upper Bound on the Decay tau -> mu gamma from Belle
K. Abe
We have performed a search for the lepton-flavor-violating decay tau -> mu gamma using a data sample of 86.3fb^{-1} accumulated by the Belle detector at KEK. No evidence for a sign…
Observation of B+ -> p pbar pi+, B0 -> p pbar K0, and B+ -> p pbar K*+
M. -Z. Wang
We report the first observation of a b -> u type charmless baryonic B decay, B+ -> p pbar pi+, as well as b -> s type B0 -> p pbar K0 and B+ -> p pbar K*+ decays. The analysis is b…
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…
