argumentDistillation model calculationsforThis argument, if it holds, bears in favour of the claim.constitution →

Given that heavy-ion collisions can form a baryon-rich quark-gluon plasma and that the transition at high baryon density is first order, phase coexistence lets the system separate strangeness: because kaon emission carries antistrange quarks away while strange quarks remain, the plasma cools into an increasingly strange, increasingly bound droplet. Model calculations along this chain (Greiner, Koch and Stöcker, Phys. Rev. D 38, 2797; Greiner and Stöcker, Phys. Rev. D 44, 3517) find yields far above those of competing mechanisms, so if the distilled droplet survives hadronization and evaporation, distillation is the dominant production channel.

argumentSpeculative preconditions and empirical absenceagainstThis argument, if it holds, weighs against the claim.constitution →

The distillation scenario stacks several unestablished preconditions, whereas coalescence of produced hyperons requires only ordinary hadron dynamics; if strangelet production proceeds mainly through coalescence of baryons, distillation does not dominate it. Moreover, because no strangelet has been observed in heavy-ion collision experiments, including dedicated searches at the baryon-rich AGS and SPS energies where distillation predicts its largest yields, the quantitative model predictions that constitute the positive case for dominance have failed their only empirical test.
