Determining Heavy Hybrid Masses via QCD Sum Rules
Cong-Feng Qiao, Liang Tang, Gang Hao +1
The masses of charmonium and bottomonium hybrids are evaluated in terms of QCD sum rules. We find that the ground state hybrid in charm sector lies in $m_{H_c}=4.12\sim 4.…
Pseudoscalar Quarkonium Exclusive Decays to Vector Meson Pair
Peng Sun, Gang Hao, Cong-Feng Qiao
The pseudoscalar quarkonia exclusive decays to light mesons still poses a challenge to the theoretical understanding of quarkonium properties in decay. In this work, we evaluate th…
The Fragmentation Function of Gluon Splitting into P-wave Spin-singlet Heavy Quarkonium
Gang Hao, YaBing Zuo, Cong-Feng Qiao
The gluon fragmentation function of at leading order of strong coupling constant and typical velocity is calculated in the framework of NRQCD, of which the co…
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…
Hunting eta_b through radiative decay into J/psi
Gang Hao, Yu Jia, Cong-Feng Qiao +1
We propose that the radiative decay process, η_b\to J/ψγ, may serve as a clean searching mode for η_b in hadron collision facilities. By a perturbative QCD calculation, we estimate…
Asymmetry in Photoproduction
Gang Hao, Lin Li, Cong-Feng Qiao
By adopting two models of strange and antistrange quark distributions inside nucleon, the light-cone meson-baryon fluctuation model and the effective chiral quark model, we calcula…
