Description

We systematically investigate the weak decays of the doubly charmed baryons, which are helpful for experimental searches for these particles. The branching fractions are studied under the factorization hypothesis for the short-distance contributions and considering the rescattering effect for the long-distance contributions which are significantly enhanced. Comparing all the decay modes, we recommend the processes of $\Xi_{cc}^{++}\to\Lambda_c^+ K^- \pi^+ \pi^+$ and $\Xi_c^+ \pi^+$ as the first priority for experiments to search for the doubly heavy baryons. The LHCb collaboration successfully observed the first double-charm baryon via the decay mode $\Xi_{cc}^{++}\to\Lambda_c^+ K^- \pi^+ \pi^+$ under our suggestion.
