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…

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…

Measurements of time-dependent CP asymmetries in $B \to D^{*\mp} π^{\pm}$ decays using a partial reconstruction technique

S. Bahinipati, K. Trabelsi, K. Kinoshita

We report results on time-dependent CP asymmetries in $B \to D^{*\mp} π^{\pm}$ decays based on a data sample containing 657 {\times} $1 0^{6}$ $B B ˉ$ pairs collected with the Belle…

Search for CP Violation in the Decays $D^{0} \to K_{S}^{0} P^{0}$

B. R. Ko, E. Won

We have searched for CP violation in the decays $D^{0} \to K_{S}^{0} P^{0}$ where $P^{0}$ denotes a neutral pseudo-scalar meson which is either a $π^{0}$ , $η$ , or $η^{'}$ using KEKB asymme…
