Abstract

We perform a systematical investigation of the possible deuteron-like bound states with configuration ΞccN(Nˉ)\Xi_{cc}N (\bar{N}), where N(Nˉ)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{}^3S_1 and 3D1{}^3D_1 channels due to non-vanishing tensor force. There exist several candidates of the loosely bound molecular states for the ΞccN\Xi_{cc}N and ΞccNˉ\Xi_{cc}\bar{N} systems, which lie below the threshold of ΛcΛc\Lambda_c\Lambda_c or ΛcΛˉc\Lambda_c{\bar\Lambda}_c. We also investigate the possible loosely bound states with configurations ΛcN(Nˉ)\Lambda_cN(\bar{N}) and ΣcN(Nˉ)\Sigma_cN(\bar{N}). These molecular candidates may be searched for at Belle II and LHC in the near future.
