Phase-constrained $Σ^{*}$ spectroscopy in the pure- $I = 1$ reactions $K_{L} p \to π^{+} Σ^{0}$ and $K_{L} p \to π^{+} Λ$

Dan Guo, Marshall B. C. Scott, Igor Strakovsky +2

Low-energy $K ˉ N$ scattering provides direct access to strange-baryon spectroscopy, but conventional charged-kaon reactions mix the $I = 0$ and $I = 1$ amplitudes. Motivated by the…

Understanding the enhanced $ϕ η^{'}$ decay mode of the $ϕ (2170)$ through strange-meson loops

Qin-Song Zhou, Jun-Zhang Wang, Dan Guo

The nature of the strangeonium-like $ϕ (2170)$ remains controversial. Recent measurements of $e^{+} e^{-} \to ϕ η^{(')}$ reveal a striking puzzle: a broad $ϕ (2170)$ -like structure appe…

Analysis of $Σ^{*}$ via isospin selective reaction $K_{L} p \to π^{+} Σ^{0}$

Dan Guo, Jun Shi, Igor Strakovsky +1

The isospin-selective reaction $K_{L} p \to π^{+} Σ^{0}$ provides a clean probe for investigating $I = 1$ $Σ^{*}$ resonances. In this work, we perform an analysis of this reaction using an eff…

Pion photoproduction of nucleon excited states with Hamiltonian effective field theory

Yu Zhuge, Zhan-Wei Liu, Derek B. Leinweber +1

We refine our previous calculation of multipole amplitude $E_{0 +}$ for pion photoproduction process, $γ N \to π N$ . The treatment of final-state interactions is based upon an e…

Structure of the $Λ (1670)$ resonance

Jiong-Jiong Liu, Zhan-Wei Liu, Kan Chen +4

We examine the internal structure of the $Λ (1670)$ through an analysis of lattice QCD simulations and experimental data within Hamiltonian effective field theory. Two scenarios are…

Connection between near the $D_{s}^{+} D_{s}^{-}$ threshold enhancement in $B^{+} \to D_{s}^{+} D_{s}^{-} K^{+}$ and conventional charmonium $χ_{c 0} (2 P)$

Dan Guo, Jun-Zhang Wang, Dian-Yong Chen +1

Focusing on recent measurement of $B^{+} \to D_{s}^{+} D_{s}^{-} K^{+}$ process given by the LHCb Collaboration, we propose that this newly observed near the $D_{s}^{+} D_{s}^{-}$ threshold enhancement c…

Newly observed $a_{0} (1817)$ as the scaling point of constructing the scalar meson spectroscopy

Dan Guo, Wei Chen, Hua-Xing Chen +2

Stimulated by the newly observed $a_{0} (1817)$ by the BESIII Collaboration, we find a perfect Regge trajectory composed of the $a_{0} (980)$ , $a_{0} (1450)$ , and $a_{0} (1817)$ , which leads u…
