The decay properties of two- and three- gluon glueballs
Wei-Han Tan, Hua-Xing Chen, Ding-Kun Lian +1
We previously studied the decay properties of two- and three-gluon glueballs using the Fierz rearrangement method and obtained their relative branching ratios in Ref.~\cite{Tan:202…
Light tetraquark states with from QCD sum rules
Yi-Wei Jiang, Hua-Xing Chen, Er-Liang Cui +3
We perform a systematic QCD sum rule study of light tetraquark states with in the diquark--antidiquark picture. A complete set of local interpolating currents is co…
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…
Investigations on heavy quarkonium hybrid mesons with exotic quantum numbers
Qi-Nan Wang, Ding-Kun Lian, Hua-Xing Chen +1
We investigate the heavy quarkonium hybrid mesons with exotic quantum numbers via QCD sum rule method. We construct the currents with three Lorentz indices and calc…
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})…
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…
