Deuteron-like states composed of two doubly charmed baryons

Abstract

We present a systematic investigation of the possible molecular states composed of a pair of doubly charmed baryons (${\Xi }_{cc}{\Xi }_{cc}$) or one doubly charmed baryon and one doubly charmed antibaryon $({\Xi }_{cc}{\bar{\Xi }}_{cc})$ within the framework of the one-boson-exchange-potential model. For the spin-triplet systems, we take into account the mixing between the ${}^3{S}_1$ and ${}^3{D}_1$ channels. For the baryon-baryon system ${\Xi }_{cc}{\Xi }_{cc}$ with $(R,I)=(\bar{3},1/2)$ and $(\bar{3},0)$, where $R$ and $I$ represent the group representation and the isospin of the system, respectively, there exist loosely bound molecular states. For the baryon-antibaryon system ${\Xi }_{cc}{\bar{\Xi }}_{cc}$ with $(R,I)=(8,1)$, $(8,1/2)$ and $(8,0)$, there also exist deuteron-like molecules. The $B_{cc}{\bar{B}}_{cc}$ molecular states may be produced at LHC. The proximity of their masses to the threshold of two doubly charmed baryons provides a clean clue to identify them.
