Heavy quark spin multiplet structure of ${\overline{P}}^{(*)}{\Sigma}_{Q}^{(*)}$ molecular states
/ Shimizu, Yuki ; Yamaguchi, Yasuhiro ; Harada, Masayasu
We study the structure of heavy quark spin (HQS) multiplets for heavy mesonbaryon molecular states in a coupled system of ${\overline{P}}^{(*)}{\Sigma}_{Q}^{(*)}$, constructing the onepion exchange potential with Swave orbital angular momentum. [...]

Analysis of ${\Lambda}_{c}\left(2595\right)$, ${\Lambda}_{c}\left(2625\right)$, ${\Lambda}_{b}\left(5912\right)$, ${\Lambda}_{b}\left(5920\right)$ based on a chiral partner structure
/ Kawakami, Yohei ; Harada, Masayasu
We construct an effective hadronic model including ${\Lambda}_{c}\left(2595\right)$, ${\Lambda}_{c}\left(2625\right)$, ${\Lambda}_{b}\left(5912\right)$, and ${\Lambda}_{b}\left(5920\right)$, regarding them as chiral partners to ${\Sigma}_{c}\left(2455\right)$, ${\Sigma}_{c}\left(2520\right)$, ${\Sigma}_{b}$, and ${\Sigma}_{b}^{*}$, respectively, with respecting the chiral symmetry and heavyquark spinflavor symmetry.

Relation between the mass modification of heavy–light mesons and the chiral symmetry structure in dense matter
/ Harada, Masayasu ; Ma, YongLiang ; Suenaga, Daiki ; Takeda, Yusuke
We point out that the study of the density dependences of the masses of heavy–light mesons gives some clues to the chiral symmetry structure in nuclear matter. [...]
