Search for Strangeness at new Ultra-relativistic Heavy-ion Colliders

The Relativistic Heavy-Ion Collider (RHIC) is operating since a few months. The Large Hadron Collider (LHC) will be operational around 2005. They will be served by several experiments of considerable scale. Among them, the STAR and the ALICE experiments are dedicated to the study of fundamental aspects linked to an expected phase transition between the hadronic and a deconfined-quark state of nuclear matter. Numerous experimental approaches are offered by the versatility of these experiments, one of the most effective is the study of the strangeness production. An expected intringing form of strangeness is the Ho, the result of a uuddss quark state or of a 2Lambdao aggregation. The presentation will deal with the strangeness study and with possible experimental attempts to identify such a Ho nuclear state, thus extending the promising general study of strangeness.
