Prediction of triple-charm molecular pentaquarks

Abstract

In a one-boson-exchange model, we study molecular states of double-charm baryon (${\Xi }_{cc}(3621)$) and a charmed meson ($D$ and $D^{\ast }$). Our model indicates that there exist two possible triple-charm molecular pentaquarks, a ${\Xi }_{cc}D$ state with $I(J^P)=0(1/2^{-})$ and a ${\Xi }_{cc}{D}^{\ast }$ state with $I(J^P)=0(3/2^{-})$. In addition, we also extend our formula to explore ${\Xi }_{cc}{\bar{B}}^{(\ast )}$, ${\Xi }_{cc}{\bar{D}}^{(\ast )}$, and ${\Xi }_{cc}{B}^{(\ast )}$ systems, and find more possible heavy flavor molecular pentaquarks, a ${\Xi }_{cc}\bar{B}$ state with $I(J^P)=0(1/2^{-})$, a ${\Xi }_{cc}{\bar{B}}^{\ast }$ state with $I(J^P)=0(3/2^{-})$, and ${\Xi }_{cc}{\bar{D}}^{\ast }/{\Xi }_{cc}{B}^{\ast }$ states with $I(J^P)=0(1/2^{-})$. Experimental search for these predicted triple-charm molecular pentaquarks is encouraged.
