$\Omega_{ccc}$ Production in High Energy Nuclear Collisions

TL;DR

This paper studies the production of the triply charmed baryon $\\Omega_{ccc}$ in high energy nuclear collisions, showing it is significantly more likely to be produced in heavy ion collisions at LHC, indicating quark-gluon plasma formation.

Contribution

It introduces a new calculation of $\\Omega_{ccc}$ production using quark coalescence and solves its wave function via the hyperspherical method, providing predictions for heavy ion collisions.

Findings

Production cross section in Pb+Pb collisions is about 9 nb.

Production in heavy ion collisions is at least 100 times larger than in p+p collisions.

Observation of $\\Omega_{ccc}$ would signal quark-gluon plasma formation.

Abstract

We investigate the production of $\Omega_{ccc}$ baryon in high energy nuclear collisions via quark coalescence mechanism. The wave function of $\Omega_{ccc}$ is solved from the Schr\"odinger equation for the bound state of three charm quarks by using the hyperspherical method. The production cross section of $\Omega_{ccc}$ per binary collision in a central Pb+Pb collision at $\sqrt{s_{NN}}=2.76$ TeV reaches 9 nb, which is at least two orders of magnitude larger than that in a p+p collision at the same energy. Therefore, it is most probable to discover $\Omega_{ccc}$ in heavy ion collisions at LHC, and the observation will be a clear signature of the quark-gluon plasma formation.
