ΩcccΩccc production in high energy nuclear collisions

We investigate the production of ΩcccΩccc baryon in high energy nuclear collisions via quark coalescence mechanism. The wave function of ΩcccΩccc is solved from the Schrödinger equation for the bound state of three charm quarks by using the hyperspherical method. The production cross section of ΩcccΩccc per binary collision in a central Pb+Pb collision at sNN=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 ΩcccΩccc in heavy ion collisions at LHC, and the observation will be a clear signature of the quark–gluon plasma formation.
