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…
Tests of a particle flow algorithm with CALICE test beam data
The CALICE Collaboration
The studies presented in this paper provide a first experimental test of the Particle Flow Algorithm (PFA) concept using data recorded in high granularity calorimeters. Pairs of ov…
Heavy quark spin structure in Z_b resonances
A. E. Bondar, A. Garmash, A. I. Milstein +2
We discuss the heavy quark spin structure of the recently observed `twin' resonances and assuming that these are mostly of a `molecular' type, i.e. that t…
Study of B^{+-} -> K^{+-}(K_S K pi)^0 Decay and Determination of eta_c and eta_c(2S) Parameters
Belle collaboration, A. Vinokurova, A. Kuzmin +143
We report the results of a study of and decays followed by and decays to . The results are obtained f…
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…
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…
