Low-energy scattering in lattice QCD
Pan-Pan Shi, Feng-Kun Guo, Chuan Liu +4
The authors perform the first lattice QCD study of low‑energy DD scattering in the I(J^P)=1(0^+) and 0(1^-) channels, extracting scattering lengths and effective ranges using Lüsch…
How to understand the resonance from the quark model and -wave phase shift
Wen-Ze Zhao, Ru-Hui Ni, Jia-Jun Wu
As the lightest isovector vector meson, the meson is an important object for investigating the structure of resonant states in strong interactions. Owing to its strong couplin…
Unified study of hyperon semileptonic decays in a relativistic three-quark model
Ru-Hui Ni, Zhen-Yang Wang, Jia-Jun Wu +1
We present a unified theoretical study of semileptonic decays of ground-state octet hyperons using the relativistic three-quark model (R3QM). A key innovation of our approach is th…
A Paradigm for the Coupled-Channel Origin of Resonances: the Exotic in
Zhi Yang, Guang-Juan Wang, Jia-Jun Wu +1
The state observed in the decay provides direct evidence for an isovector open-charm tetraquark state with strangeness--a discover…
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…
Hyperon-Nucleon Spectrometer
Xiaozhi Bai, Xu Cao, Zhe Cao +237
Chirality lies at the heart of low-energy QCD, governing the symmetry structure that shapes hadron masses and strong interaction dynamics. Among the most compelling open questions…
