Evidence for Direct CP Violation in and Observation of
C. -T. Hoi, P. Chang
We report measurements of the branching fractions and CP asymmetries for B^+- -> eta h^+- (h = K or pi) and the observation of the decay B^0 -> eta K^0 from the final data sample o…
Search for charmonium and charmonium-like states in Υ(2S) radiative decays
X. L. Wang, C. P. Shen, C. Z. Yuan +2
Using a sample of 158 million Υ(2S) events collected with the Belle detector, charmonium and charmonium-like states with even charge parity are searched for in Υ(2S) radiative deca…
Bounds on the width, mass difference and other properties of X(3872) --> pi+pi-J/psi decays
S. -K. Choi, S. L. Olsen, K. Trabelsi
We present results from a study of X(3872) --> pi+pi- J/psi decays produced via exclusive B--> K X(3872) decays. We determine the mass to be M_X(3872)= (3871.84\pm 0.27 (stat)\pm 0…
First Observation of Radiative B^0 -> ϕK^0 γDecays and Measurements of Their Time-Dependent CP Violation
H. Sahoo, T. E. Browder
We report the first observation of the radiative decay B^0 -> ϕK^0 γusing a data sample of 772 x 10^6 B B-bar pairs collected at the Υ(4S) resonance with the Belle detector at the…
