Precise measurement of hadronic -decays in modes with mesons

The Belle Collaboration, K. Abe

We have measured branching fractions of hadronic decays involving an meson using 485 fb^{-1} of data collected with the Belle detector at the KEKB asymmetric-energy e^+e^-…

Measurement of CP Asymmetry in a Time-Dependent Dalitz Analysis of B^0 \to (ρπ)^0 and a Constraint on the Quark Mixing Matrix Angle ϕ_2

The Belle Collaboration, A. Kusaka, C. C. Wang +1

We present a measurement of CP asymmetry using a time-dependent Dalitz plot analysis of B0 --> pi+pi-pi0 decays based on a 414/fb data sample containing 449M BB pairs. The data was…

Evidence for B-> eta' pi and improved measurements for B-> eta' K

The Belle Collaboration, J. Schuemann

We report evidence for exclusive two-body charmless hadronic B meson decays B-> eta' pi, and improved measurements of B-> eta' K. The results are obtained from a data sample of 386…

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 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…
