Searching for $\Xi_{cc}^+$ in Relativistic Heavy Ion Collisions

TL;DR

This paper investigates the production of the doubly charmed baryon $\\Xi_{cc}^+$ in high energy nuclear collisions, predicting a significant enhancement in heavy ion collisions that could serve as a probe for quark-gluon plasma formation.

Contribution

It introduces a relativistic three-body Schrödinger equation approach and calculates the yield and momentum distribution of $\\Xi_{cc}^+$ in heavy ion collisions, highlighting its increased production.

Findings

Yield of $\\Xi_{cc}^+$ is highly enhanced in central Pb+Pb collisions at LHC.

Production cross section per binary collision is ten times larger than in p+p collisions.

Discovery of $\\Xi_{cc}^+$ in heavy ion collisions can indicate quark-gluon plasma formation.

Abstract

We study the doubly charmed baryon $\Xi_{cc}^+$ in high energy nuclear collisions. We solve the three-body Schroedinger equation with relativistic correction and calculate the $\Xi_{cc}^+$ yield and transverse momentum distribution via coalescence mechanism. For $\Xi_{cc}^+$ production in central Pb+Pb collisions at LHC energy, the yield is extremely enhanced, and the production cross section per binary collision is one order of magnitude larger than that in p+p collisions. This indicates that, it is most probable to discover $\Xi_{cc}^+$ in heavy ion collisions and its discovery can be considered as a probe of the quark-luon plasma formation.
