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

Vector and Axialvector form factors in radiative kaon decay and flavor SU(3) symmetry breaking
/ Shim, SangIn ; Hosaka, Atsushi ; Kim, HyunChul
We study the vector and axialvector 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. [...]

Emergence of a Complete HeavyQuark Spin Symmetry Multiplet: Seven Molecular Pentaquarks in Light of the Latest LHCb Analysis
/ Liu, MingZhu ; Pan, YaWen ; Peng, FangZheng ; Sánchez, Mario Sánchez ; et al
A recent analysis by the LHCb Collaboration suggests the existence of three narrow pentaquarklike states—the ${P}_{c}\left(4312\right)$, ${P}_{c}\left(4440\right)$, and ${P}_{c}\left(4457\right)$—instead of just one in the previous analysis [the ${P}_{c}\left(4450\right)$]. [...]

Identifying the ${\Xi}_{b}\left(6227\right)$ and ${\Sigma}_{b}\left(6097\right)$ as $P$wave bottom baryons of ${J}^{P}=3/{2}^{}$
/ Cui, ErLiang ; Yang, HuiMin ; Chen, HuaXing ; 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 ${\Sigma}_{b}(6097{)}^{\pm}$ and ${\Xi}_{b}(6227{)}^{}$, and use the method of light cone sum rules still within the heavy quark effective theory to study their decay properties.

Exotic triplecharm deuteronlike hexaquarks
/ Chen, Rui ; Wang, FuLai ; Hosaka, Atsushi ; Liu, Xiang
Adopting the onebosonexchange model, we perform a systematic investigation of interactions between a doubly charmed baryon $\left({\Xi}_{cc}\right)$ and an $S$wave charmed baryon (${\Lambda}_{c}$, ${\Sigma}_{c}^{(*)}$, and ${\Xi}_{c}^{(\prime ,*)}$). [...]

Searching for possible ${\Omega}_{c}$like molecular states from mesonbaryon interaction
/ Chen, Rui ; Hosaka, Atsushi ; Liu, Xiang
Stimulated by the recent observation of ${\Omega}_{c}$ as well as past observations of ${P}_{c}\left(4380\right)$ and ${P}_{c}\left(4450\right)$, we perform a coupledchannel analysis of ${\Xi}_{c}^{*}\overline{K}/{\Omega}_{c}\eta /{\Omega}_{c}^{*}\eta /{\Xi}_{c}{\overline{K}}^{*}/{\Xi}_{c}^{\prime}{\overline{K}}^{*}/{\Omega}_{c}\omega $ systems to search for possible ${\Omega}_{c}$like molecular states by using a onebosonexchange potential.
