and molecular states
J. M. Dias, Qi-Xin Yu, Wei-Hong Liang +3
Using the vector-exchange interaction in the local hidden gauge approach, which in the light quark sector generates the chiral Lagrangian, and has produced realistic results for $Ω…
Molecular states from meson-baryon interaction
Qi-Xin Yu, J. M. Dias, Wei-Hong Liang +1
We have studied the meson-baryon interaction in coupled channels with the same quantum numbers of . The interaction is attractive in some channels and of sufficient intensi…
as a molecule in the Bethe-Salpeter equation approach
Zhen-Yang Wang, Jing-Juan Qi, Qi-Xin Yu +1
We interpret the as an -wave molecular state in the Bethe-Salpeter equation approach. In the ladder and instantaneous approximations, and with the…
Masses of doubly heavy baryons in the Bethe-Salpeter equation approach
Qi-Xin Yu, Xin-Heng Guo
A doubly heavy baryon can be regarded as composed of a heavy diquark and a light quark. In this picture, we study the masses of the doubly heavy diquarkes in the Bethe-Salpeter (BS…
Residues of -type and -type Baryons in the Bethe-Salpeter Equation Approach
Qi-Xin Yu, Zhen-Yang Wang, Jing-Juan Qi +1
We study the residues of -type baryons ( and ) and -type baryons (, and ) in the quark-diquark model wit…
