Abstract
We reconsider thermal conditions of the central fireball presumed to b e the source of abundantly produced strange (anti-) baryons in S --> W collisions at 200 GeV A. We show that it is possible to completely fi x the freeze-out temperature of strange particles in terms of the cent ral rapidity kaon to Lambda particle abundance ratio at fixed, high tr ansverse mass using a non-equilibrium hadronization model and the meas ured quark fugacities.
