Description
We first study the doubly charmed baryon $\Xi_{cc}^+$ structure and yield in high energy nuclear collisions. Using hypericspherical expansion method, we solved the three-body Schr¨odinger equation including relativistic correction and calculate the yield of $\Xi_{cc}^+$ via coalescence mechanism. We find that, the $\Xi_{cc}^+$ created in heavy ion collision is like a quark-diquark state as a consequence of chiral symmetry restoration in hot medium, and the yield is extremely enhanced due to the large number of charm quarks.
