Investigation of the bottomonium ground state η_b via its inclusive charm decays
Gang Hao, Cong-Feng Qiao, Peng Sun
Based on the non-relativistic QCD factorization formalism, we calculate the bottomonium ground state, , inclusive charm decays at the leading order in the strong coupling cons…
A Uniform Description of the States Recently Observed at B-factories
Cong-Feng Qiao
The newly found states Y(4260), Y(4361), Y(4664) and Z(4430) stir broad interest in the study of spectroscopy in a typical charmonium scale. The Y(4260) which was observed ea…
On the Application of Gluon to Heavy Quarkonium Fragmentation Functions
W. Qi, C. F. Qiao, J. X. Wang
We analyze the uncertainties induced by different definitions of the momentum fraction in the application of gluon to heavy quarkonium fragmentation function. We numerically ca…
B Physics and Hadronic Matrix Elements
C-H Chang, K-T Chao, X-G He +10
In a mini workshop on B Physics which were held at Dalian, China, a number of lectures was given. Around 40 participants joined the workshop. In this workshop, people discussed the…
Gluon fragmentation to quarkonium and test of color-octet production mechanism
Kuang-Ta Chao, Cong-Feng Qiao, Feng Yuan
We report the recent progress in the studies of D-wave heavy quarkonia production from gluon fragmentation at the Tevatron and in Z^0 decays, and the D-wave charmonia production in…
Nuclear Effects on Charmonium Production
Xiao-Fei Zhang, Cong-Feng Qiao, Xiao-Xia Yao +1
and production cross sections in fixed-target experiment is calculated, considering the contributions from both color-singlet and color-octet mechanisms.The results are…
