Abstract

Adopting the one-boson-exchange model, we perform a systematic investigation of interactions between a doubly charmed baryon (Ξcc)(\Xi_{cc}) and an SS-wave charmed baryon (Λc\Lambda_c, Σc()\Sigma_c^{(*)}, and Ξc(,)\Xi_c^{(\prime,*)}). Both the SS-DD 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 SS-wave anticharmed baryon. We find that a doubly charmed baryon and an SS-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.
