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…
Development of Bethe-Salpeter theory for dealing with unstable system
Xiaozhao Chen, Xiaofu Lü
In the framework of relativistic quantum field theory, the solution of homogeneous Bethe-Salpeter equation for two-body bound state can not describe unstable system, so we develop…
Calculation of mass and width of unstable molecular state using the developed Bethe-Salpeter theory
Xiaozhao Chen, Xiaofu Lü, Xiurong Guo +2
Applying the developed Bethe-Salpeter theory for dealing with resonance, we investigate the time evolution of molecular state composed of two vector mesons as determined by the tot…
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…
