Abstract：
The existence of doubly heavy flavor baryons has not been well established experimentally so far. In this Letter we systematically investigate the weak decays of the doubly charmed baryons, Ξ_cc⁺⁺ and Ξ_cc⁺, which should be helpful for experimental searches for these particles. The long-distance contributions are first studied in the doubly heavy baryon decays, and found to be significantly enhanced. Comparing all the processes, Ξ_cc⁺⁺→ Λ_c⁺K^-π⁺π⁺ and Ξ_c⁺π⁺ are the most favorable decay modes for experiments to search for doubly heavy baryons.
