An improved moment QCD sum rule
Jin-Peng Zhang, Xu-Liang Chen, Wei Chen
QCD sum rules are among the most important non-perturbative tools in hadron physics, with the Laplace sum rule (LSR) and moment sum rule (MSR) being the two most commonly used form…
Interpretation of as a molecular state
Xiang Yu, Jin-Peng Zhang, Xu-Liang Chen +3
We investigate the mass and strong decay properties of the resonance using QCD sum rules, assuming it to be an S-wave molecular pentaquark state with $I(…
Study of the and dibaryons in QCD Sum Rules
Xu-Liang Chen, Jin-Peng Zhang, Zi-Xi Ou-Yang +2
The recent observation of a family of fully-charm tetraquark states by the LHCb, ATLAS and CMS Collaborations suggests the possible existence of fully-heavy dibaryons. In this work…
Three-body molecular states composed of and two nucleons
Si-Yi Chen, Fei-Yu Chen, Xu-Liang Chen +3
We study the three-body systems and within a hadronic molecular framework by combining a realistic nucleon-nucleon interaction with a potential constrain…
Doubly charmed pentaquark states with strangeness
Wei Chen, Feng-Bo Duan, Zi-Yan Yang +3
In this work, we have studied the mass spectra of doubly charmed pentaquark states with strangeness by using the method of QCD sum rules. We use the parity projected sum…
Unraveling as a pseudoscalar tetraquark state
Jin-Peng Zhang, Xu-Liang Chen, Zi-Xi Ou-Yang +3
The recent observed has been identified as a supernumerary pseudoscalar resonance signal in the strange-meson spectrum predicted by quark model calculations. It is the b…
Possible bound states in the triple- and triple- systems
Guo-Feng Xu, Xu-Liang Chen, Jin-Peng Zhang +2
The observations of fully-charm tetraquark states in the LHCb, CMS and ATLAS experiments suggested the existence of the hadronic molecules of two-charmonium states, which may also…
Mixing angle of and the molecular interpretation of
Zheng-Shu Liu, Xu-Liang Chen, Ding-Kun Lian +2
Due to the SU(3) symmetry breaking effect, the axial-vector kaons and are established to be mixtures of two P-wave and $K_{…
Towards heavy double-gluon hybrid mesons with exotic quantum numbers in QCD sum rules
Ding-Kun Lian, Qi-Nan Wang, Xu-Liang Chen +3
The double-gluon hybrid meson configuration was recently proposed and investigated within QCD sum rules. In this talk, we discuss the color structures of the double-gluon hybrid me…
Discontinuities of banana integrals in dispersion relation representation
Xu-Liang Chen, Peng-Fei Yang, Wei Chen
We derive the discontinuities of banana integrals using the dispersion relation iteratively. We find a series of identities between the parameterized discontinuities of banana inte…
Revisit the heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers
Ding-Kun Lian, Qi-Nan Wang, Xu-Liang Chen +3
We revisit the masses of heavy quarkonium double-gluon hybrid mesons with exotic quantum numbers and in the framework of the QCD sum rules. Considering the…

Feng-Bo Duan, Qi-Nan Wang, Zi-Yan Yang +2
We have studied the mass spectra of doubly charmed pentaquark states in the and channels with , and withi…
