Abstract

The kinetic equations for production in hot nuclear matter of rare, strange antibaryons are studied numerically. Strange antibaryons are confirmed as viable characteristic signatures of the quark-gluon plasma. We find four orders of magnitude enhancement in the abundance of Ω multiply-strange antibaryons. Strange antibaryon production in the hadronic gas phase is shown to have a relatively slow characteristic time constant of ∼ 10^-21 sec to be compared with the 100 times faster equilibration in quark-gluon plasma.
