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 CP Violation in D Meson Decays to phi pi+
Belle Collaboration, M. Starič, H. Aihara +132
We search for CP violation in Cabibbo-suppressed charged D meson decays by measuring the difference between the CP violating asymmetries for the Cabibbo-suppressed decays D+ -> K+K…
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…
Observation of B- to pbar Lambda D0 at Belle
P. Chen, M. -Z. Wang, I. Adachi +137
We study B- meson decays to pbar Lambda D(*)0 final states using a sample of 657 * 10^6 B Bbar events collected at the Upsilon(4S) resonance with the Belle detector at the KEKB asy…
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…

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…
Observation of transverse polarization asymmetries of charged pion pairs in e+e- annihilation near sqrt s=10.58 GeV
A. Vossen, R. Seidl, I. Adachi +97
The interference fragmentation function translates the fragmentation of a quark with a transverse projection of the spin into an azimuthal asymmetry of two final-state hadrons. In…

Belle Collaboration, Y. Horii, K. Trabelsi +143
The suppressed decay chain B- -> DK-, D -> K+pi-, where D indicates a anti-D0 or D0 state, provides important information on the CP-violating angle phi_3. We measure the ratio R_{D…
