Glueballs amass at the RHIC and LHC! The early quarkless first-order phase transition at T = 270 MeV—from pure Yang–Mills glue plasma to Hagedorn glueball states

The early stage of a high multiplicity pp, pA and AA collisions is represented by a nearly quarkless, hot, deconfined pure gluon plasma. According to pure Yang–Mills lattice gauge theory, this hot pure glue matter undergoes, at a high temperature, $T_c=270MeV,$ a first-order phase transition into a confined Hagedorn glueball fluid. This new scenario should be characterized by a suppression of high p _T photons and dileptons, baryon suppression and enhanced strange meson production. We propose to observe this newly predicted class of events at the Large Hadron Collider and the Relativistic Heavy-Ion Collider. (paper)
