Exotic triple-charm deuteron-like hexaquarks

Abstract

Adopting the one-boson-exchange model, we perform a systematic investigation of interactions between a doubly charmed baryon $({\Xi }_{cc})$ and an $S$-wave charmed baryon (${\Lambda }_c$, ${\Sigma }_c^{(\ast )}$, and ${\Xi }_c^{(\prime ,\ast )}$). Both the $S$-$D$ mixing effect and coupled-channel effect are considered in this work. Our results suggest that there may exist several possible triple-charm deuteron-like hexaquarks. Meanwhile, we further study the interactions between a doubly charmed baryon and an $S$-wave anticharmed baryon. We find that a doubly charmed baryon and an $S$-wave anticharmed baryon can be easily bound together to form shallow molecular hexaquarks. These heavy flavor hexaquarks predicted here can be accessible at future experiment like LHCb.
