  The early stage of high multiplicity pp, pA and AA collider 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, $T_c = 270$ MeV, a first order phase transition into a confined
Hagedorn-GlueBall fluid. These 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 LHC and RHIC.
