Double heavy-quarkonium production from electron-positron annihilation in the Bethe-Salpeter formalism
Xin-Heng Guo, Hong-Wei Ke, Xue-Qian Li +1
In this work we evaluate the cross section of the process at energy GeV in the Bethe-Salpeter formalism. To simplify our calculation, the…
Study on production of exotic meson in decays of
Xin-Heng Guo, Hong-Wei Ke, Xue-Qian Li +2
The newly observed family containing , and attracts great interests. Determining their structure may be important tasks f…
Cabibbo-suppressed non-leptonic decays of Lambda_c and final state interaction
Shao-Long Chen, Xin-Heng Guo, Xue-Qian Li +1
With the diquark structure of Lambda_c, we investigate the branching ratios of Lambda_c -> n pi^+ and p pi^0. The results show that without considering the final state interaction…
Electromagnetic radiation of baryons containing two heavy quarks
Wu-Sheng Dai, Xin-Heng Guo, Hong-Ying Jin +1
The two heavy quarks in a baryon which contains two heavy quarks and a light one, can constitute a scalar or axial vector diquark. We study electromagnetic radiations of such baryo…
Non-Spectator Diquark Effects on Lifetimes of Λ_b, Ω_{b}^{(*)} and Weak Decay Rates of Σ_{b}^{(*)}, Ξ_{b}^{(*)}
Wu-Sheng Dai, Xin-Heng Guo, Xue-Qian Li +1
The difference of τ_{_B} and τ_{_{Λ_b}} indicates the role of the light flavors. We calculate the lifetimes of B-meson and Λ_b based on the weak effective Hamiltonian while assumin…
Possible Effects of Quantum Mechanics Violation Induced by Certain Quantum Gravity on Neutrino Oscillations
Chao-Hsi CHANG, Wu-Sheng DAI, Xue-Qian LI +3
In this work we tried extensively to apply the EHNS postulation about the quantum mechanics violation effects induced by the quantum gravity of black holes to neutrino oscillations…
Weak Semileptonic Decays of Heavy Baryons Containing Two Heavy Quarks
Xin-Heng Guo, Hong-Ying Jin, Xue-Qian Li
In the heavy quark limit a heavy baryon which contains two heavy quarks is believed to be composed of a heavy diquark and a light quark. Based on this picture, we evaluate the weak…
Possible Explanation Why τ_{B^{\pm}}\simτ_{B^0} But τ_{D^{\pm}}\sim τ_{D^0}
Hui-Shi Dong, Xin-Heng Guo, Xue-Qian Li +1
Data show that τ_{B^{\pm}}\simτ_{B^0}, but τ_{D^{\pm}}\sim 2τ_{D^0}. The naive interpretation which attributes τ_{D^{\pm}}\sim 2τ_{D^0} to a destructive interference between two qu…
Applications of the superflavor symmetry to heavy baryon-antibaryon pair production in electron-positron collision
X. -H. Guo, H. Y. Jin, X. -Q. Li
The baryons containing two heavy quarks and a light quark are believed to have the diquark-quark structure and the diquark is composed of the two heavy quarks which is a spin-0 or…
The dissipative potential induced by QCD at finite temperature and density
S. Gao, X. -H. Guo, X. -Q. Li +2
In the framework of QCD at finite temperature we have obtained dissipative terms for the effective potential between and which would partly explain the suppressi…
Study on , Decays and CP-Non Invariance at Early Epoch of the Universe
Wu-Sheng Dai, Song Gao, Xue-Qian Li
We study the and decays in the early epoch of the universe. If , there would be a CP asymmetry between and $\barν_τ \rightarr…
