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…
Subtraction of infrared divergences in light-quark QCD sum rules
Ding-Kun Lian, Jin-Peng Zhang, Zi-Xi Ou-Yang +4
In QCD sum rules for light-quark systems, infrared (IR) divergences can appear in the Wilson coefficients of certain condensates. These divergences manifest explicitly in the coord…
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…
Decay and production properties of strange double charm pentaquark
Zi-Yan Yang, Wei Chen
In this work we investigate the decay and production properties of the strange double-charm pentaquark with strangeness . Building upon our previous work predi…
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…
Light hybrid baryons in QCD sum rules
Wei Chen, Qi-Nan Wang, Ding-Kun Lian +4
We have calculated the mass spectra of nucleon and delta hybrid baryons with both positive-parity and negative-parity by using the method of QCD sum rules. We predicte that the low…
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…
Interpreting the and as light tetraquark states
Qi-Nan Wang, Ding-Kun Lian, Wei Chen
Inspired by the states and reported by the BESIII Collaboration, we systematically investigate the mass spectra of light compact tetraquark states with configur…
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_{…
Predictions of masses for light hybrid baryons
Qi-Nan Wang, Ding-Kun Lian, Wei Chen +4
Within the method of parity-projected QCD sum rules, we study the mass spectra of light hybrid baryons with $I(J^{P})=1/2(1/2^{\pm}), 3/2(1/2^{\pm}), 1/2(3/2^{\pm}), 3/2(3/2^{\pm})…
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…

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…
