1. Search of QCD phase transition points in the canonical approach of the NJL model / Wakayama, Masayuki ; Hosaka, Atsushi
We study the Lee-Yang zeros in the canonical approach to search phase transition points at finite temperature and density in the Nambu-Jona-Lasinio (NJL) model as an effective model of QCD. [...]

2. Vector and Axial-vector form factors in radiative kaon decay and flavor SU(3) symmetry breaking / Shim, Sang-In ; Hosaka, Atsushi ; Kim, Hyun-Chul
We study the vector and axial-vector form factors of radiative kaon decay within the framework of the gauged nonlocal effective chiral action from the instanton vacuum, focusing on the effects of flavor SU(3) symmetry breaking. [...]

3. Emergence of a Complete Heavy-Quark Spin Symmetry Multiplet: Seven Molecular Pentaquarks in Light of the Latest LHCb Analysis / Liu, Ming-Zhu ; Pan, Ya-Wen ; Peng, Fang-Zheng ; Sánchez, Mario Sánchez ; et al
A recent analysis by the LHCb Collaboration suggests the existence of three narrow pentaquarklike states—the Pc(4312), Pc(4440), and Pc(4457)—instead of just one in the previous analysis [the Pc(4450)]. [...]

4. Identifying the Ξb(6227) and Σb(6097) as P-wave bottom baryons of JP=3/2 / Cui, Er-Liang ; Yang, Hui-Min ; Chen, Hua-Xing ; Hosaka, Atsushi
We use the method of QCD sum rules within the framework of heavy quark effective theory to study the mass spectrum of the Σb(6097)± and Ξb(6227), and use the method of light cone sum rules still within the heavy quark effective theory to study their decay properties. [...]

5. Exotic triple-charm deuteronlike hexaquarks / Chen, Rui ; Wang, Fu-Lai ; Hosaka, Atsushi ; Liu, Xiang
Adopting the one-boson-exchange model, we perform a systematic investigation of interactions between a doubly charmed baryon (Ξcc) and an S-wave charmed baryon (Λc, Σc(*), and Ξc(,*)). [...]

6. Searching for possible Ωc-like molecular states from meson-baryon interaction / Chen, Rui ; Hosaka, Atsushi ; Liu, Xiang
Stimulated by the recent observation of Ωc as well as past observations of Pc(4380) and Pc(4450), we perform a coupled-channel analysis of Ξc*K¯/Ωcη/Ωc*η/ΞcK¯*/ΞcK¯*/Ωcω systems to search for possible Ωc-like molecular states by using a one-boson-exchange potential. [...]

7. Heavy pentaquark states P c (4380) and P c (4450) in the J / ψ production induced by pion beams off the nucleon / Kim, Sang-Ho ; Kim, Hyun-Chul ; Hosaka, Atsushi
In this study, we investigate the J/ψ production induced by pion beams off the nucleon, particularly the heavy pentaquarks Pc(4380) and Pc(4450) in intermediate states, based on a hybridized Regge model. [...]
