Unstable molecular state with unstable constituent
Yuqin Yin, Zonghua Shi, Hao Liu +3
Based on the developed Bethe-Salpeter theory for dealing with unstable state, we investigate unstable meson-meson molecular state in which at least one of the constituents is an un…

Mass and width of in the developed Bethe-Salpeter theory
Xiaozhao Chen, Xiaofu Lü, Xiurong Guo +1
In experiments exotic meson resonance lies above the threshold, and in principle one can not explain as a meson-meson bou…

Radiative decay of hadronic molecule state for quarks
Xiaozhao Chen, Xiaofu Lü, Renbin Shi +2
Using the general form of the generalized Bethe-Salpeter wave functions for four-quark states describing the meson-meson molecular structure given in our previous work, we obtain t…
