Discovery potentials of doubly charmed baryons

  • 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, Ξcc++ and Ξcc+, 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, Ξcc++→ Λc+K-π+π+ and Ξc+π+ are the most favorable decay modes for experiments to search for doubly heavy baryons.
