An improved moment QCD sum rule
Jin-Peng Zhang, Xu-Liang Chen, Wei Chen
The paper introduces an improved moment QCD sum rule (IMSR) that removes subjectivity from traditional sum‑rule analyses, allowing simultaneous determination of ground‑state masses…
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…
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…
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})…
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…
