Strange quark matter droplets in ultrarelativistic heavy ion collisions

Abstract

We present a model describing the hadronisation of the quark gluon plasma through particle emission. Pious and K +s and K 0s carry away entropy and antistrangeness from the system, thus facilitating the cooling process and the strangelet formation. The strangeness separation mechanism and the formation process works well even for higher initial entropies per baryon, tantamount to higher bombarding energies. The surviving strangelets have a rather high strangeness content, ƒ s ∼ 1.2 – 2 ( i.e. Z/A ∼ (−0.1) − (−0.5)) . Hence droplets of strange quark matter with baryon number ∼ 10 – 30 and with negative charge may be produced.
