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 3S1 and 3D1 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.
