Bound-state spectra of ${\chi }_{cJ}$ in finite nuclei and the universal pattern of mass levels

Tian-Le Gao, Ze-Hua Zhang, Xiang Liu

In this work, we investigate possible ${\chi }_{cJ}$--nuclear bound states with $J=0,1,2$ using in-medium mass shifts generated by virtual $D^{(\ast )}{\bar{D}}^{(\ast )}$ loops within an unquench…
