The project aims to study properties of hot and dense nuclear matter, produced in A+A collisions at bombarding energies between 1-16000 AGeV within the microscopic Monte Carlo models and macroscopic models at our disposal. Nowadays besides three microsco pic models, quark-gluon string model, ultra-relativistic quantum molecular dynamics, and string fusion model, we are developing two Monte Carlo code fast MC and HYDJET, which should also be employed for theoretical predictions, detector simulations and for the analysis of experimental data. The main goal of the research proposal is the exploration of the QCD phase diagram (i) in the region of high baryon densities accessible for future FAIR accelerator at GSI, and (ii) in the region of baryon-free plasma, produced at coming CERN LHC accelerator. The following issues, connected to the study of observables especially sensitive to nuclear equation of state and the formation of quark-gluon plasma, should be addressed: (i) development of anisotropic fl ow in pp and A+A system and freeze-out of particles; (ii) relaxation of highly excited nuclear matter to thermal and chemical equilibrium; (iii) extraction of the effective EOS of nuclear matter from the microscopic calculations; (iv) longitudinal and t ransverse sizes of the system obtained from the two-particle interferometry; (v) event-by-event fluctuations, (vi) to study the role of energy momentum conservation laws, quark-gluon shadowing and Cronin effects in light and heavy (J/Psi and Y) particle production. The final goal of the project is to determine the limits for microscopic models in describing heavy-ion collisions at ultra-relativistic energies. Another goal is to develop Monte Carlo Generators, based on many stage picture of heavy ion co llisions, which would include - initial state, like Color Glass Condensate, jet production, hydro expansion, jet quenching and quark-gluon shadowing, hadronization and resonance decays.
