Can X(3872) be a tetraquark state?
Chun-Yu Cui, Yong-Lu Liu, Guo-Bin Zhang +1
In this article, we test the nature of X(3872), which is assumed to be a P-wave -scalar-diquark -axial-vector-antidiquark tetraquark state with $J^{P}=2^{-}…
form factor from QCD sum rules
Chun-Yu Cui, Yong-Lu Liu, Ming-Qiu Huang
In this article, we calculate the form factors and the coupling constant of the vertex in the framework of the three-point QCD sum rules. Three point…
Investigating different structures of the Z_{b}(10610) and Z_{b}(10650)
Chun-Yu Cui, Yong-Lu Liu, Ming-Qiu Huang
The recently observed narrow resonance is examined with the assumptions both as a molecular state and a tetraquark state with q…
The exclusive rare decay b->s gamma of heavy b-Baryons
Yong-lu Liu, Long-fei Gan, Ming-qiu Huang
We present an analysis on the exclusive rare radiative decay modes Sigma_b->Sigma gamma and Xi_b->Xi gamma. The transition form factors which parameterize these processes are calcu…
Light-cone QCD sum rule approach for the baryon electromagnetic form factors and the semileptonic decay Xi_c->Xi e^+nu_e
Yong-lu Liu, Ming-qiu Huang
The electromagnetic form factors of the Xi baryons and the semileptonic decay process Xi_c->Xi e^+nu_e are investigated in the frame work of the light-cone QCD sum rule method with…
