Open AccessTwo-pole structures in a relativistic Friedrichs–Lee-QPC scheme
A general appearance of two-pole structures is exhibited in a relativistic Friedrichs–Lee model combined with a relativistic quark pair creation model in a consistent manner. This kind of two-pole structure co...

Open AccessRelativistic Friedrichs–Lee model and quark-pair creation model
In this paper, we present how the Friedrichs–Lee model could be extended to the relativistic scenario and be combined with the relativistic quark pair creation model in a consistent way. This scheme could be a...

Open AccessQCD sum rule studies on the \(s s {\bar{s}} {\bar{s}}\) tetraquark states of \(J^{PC} = 0^{-+}\)
We apply the method of QCD sum rules to study the \(s s {\bar{s}} {\bar{s}}\)sss¯s¯ tetraquark states of \(J^{PC} = 0^{-+}\)JPC=0-+. We construct all the relevant \(s s {\bar{s}} {\bar{s}}\)sss¯s¯ tetraquark curr...
