Possible hadronic molecules composed of the doubly charmed baryon and nucleon

Abstract

We perform a systematical investigation of the possible deuteron-like bound states with configuration ${\Xi }_{cc}N(\bar{N})$, where $N(\bar{N})$ denotes the nucleon (anti-nucleon), in the framework of the one-boson-exchange-potential model. In the spin-triplet sector we take into account both the ${}^3{S}_1$ and ${}^3{D}_1$ channels due to non-vanishing tensor force. There exist several candidates of the loosely bound molecular states for the ${\Xi }_{cc}N$ and ${\Xi }_{cc}\bar{N}$ systems, which lie below the threshold of ${\Lambda }_c{\Lambda }_c$ or ${\Lambda }_c{\bar{\Lambda }}_c$. We also investigate the possible loosely bound states with configurations ${\Lambda }_{c}N(\bar{N})$ and ${\Sigma }_{c}N(\bar{N})$. These molecular candidates may be searched for at Belle II and LHC in the near future.
