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...

Comprehending heavy charmonia and their decays by hadron loop effects
We present that including the hadron loop effects could help us to understand the spectrum of the heavier charmonium-like states and their strong decays simultaneously. By coupling the bare states to the opene...
