Charmed baryon semileptonic decays in a relativistic three-quark model

Ru-Hui Ni, Zhen-Yang Wang, Jia-Jun Wu +1

We study the spin- $1/2 \to 1/2$ semileptonic decays of singly charmed baryons ( $Λ_{c}^{+}$ , $Ξ_{c}^{0, +}$ , and $Ω_{c}^{0}$ ) into the light baryon octet within a relativistic three-quark model.…

First Evidence for an Unambiguous Triangle Singularity from $ψ (2 S) \to p p ˉ η$

Qi Huang, Yi-Jia Zeng, Xiao-Rui Lyu +2

Triangle singularities, predicted by Landau in 1959, are purely kinematic enhancements arising from hadronic rescattering loops. Despite their proposed role in various anomalous de…

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…

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…

Unveiling the elusive $Σ (1380)$ resonance through coupled-channel dynamics in $Λ_{c}^{+} \to η π^{+} Λ$ reaction

Wen-Tao Lyu, Si-Wei Liu, Jia-Jun Wu +2

We investigate the $Λ_{c}^{+} \to η π^{+} Λ$ decay measured by the Belle and BESIII Collaborations, focusing on the possible role of the $Σ (1380)$ state with spin-parity $J^{P} = 1/ 2^{-}$ . In o…

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…
