Abstract

The main goal of relativistic heavy ion collisions is to study nuclear matter under extreme conditions of temperature and density. It is under these conditions that it is believed that a phase transition to a new state of matter where quarks and gluons are no loger conned takes place, the so called Quarks and Gluon Plasma. Strange particle production is an important tool for the characterization of this new state of matter. Strangeness enhancement was considered as a possible evidence for the formation QGP even before the rst RHIC experimental results. In this thesis, it is determined a production of neutral strange particles K0 s and in Cu+Cu collisions at p sNN = 62:4 GeV, using a rapidity range y < j0:75j. These data are compared to theoretical models (statistical-thermodynamic, coalescence and core-corona) in order to understand the hadronization process in relativistic heavy ions collisions. (AU)
