Statistical model in the description of particle production in heavy-ion collisions (Uwaga zmiana godziny!)

During an ultrarelativistic central heavy-ion collision the number of produced particles counts in thousands. The matter created at the first stage of such collision reaches extreme values of the density in the volume of the order of the size of a nucleus. This explains the abundance of finally measured particles. To describe the production quantitatively the matter is considered as a statistical system with two independent parameters: the temperature and the baryon number chemical potential. To model the evolution of the matter relativistic hydrodynamics is applied. As an example of this approach, the gold to gold collisions at Relativistic Heavy Ion Collider (RHIC) at Brookhaven National Laboratory will be analysed successfully.
