Strange Hadrons from the ALCOR Rehadronization Model

Abstract

Hadron multiplicities --- especially for strange particles --- are calculated in the framework of the algebraic coalescence rehadronization model (ALCOR), which counts for redistribution of quarks into hadrons for relativistic heavy-ion collisions. The influence of Bjorken flow on the final hadronic composition are incorporated in the model. A comparison is made with the CERN SPS NA35 $S+S$ and $p+p$ experiments. The analysis of these experiments with ALCOR shows a strangeness enhancement for S+S collisions and a possible formation of a sort of semi-deconfined state of the matter. Predictions for Pb+Pb collisions (NA49) are also presented.
