Particle Multiplicities and Correlations

Conservation of Particle Multiplicities between Chemical and Thermal Freeze-out

The evolution of a hadronic system after its chemical decomposition is described through a model that conserves the hadronic multiplicities to their values at chemical freeze-out. In the partition function describing the model all known hadronic resonances with masses up to 2400 MeV have been included. The state of the system is found as function of temperature and the corresponding baryon dens...

Three-Particle Azimuthal Correlations

Two-particle azimuthal correlations in central Au+Au collisional at RHIC have revealed a broadened away-side structure, with respect to perpherial Au+Au, pp, and d+Au. This could be explained by different physics mechanisms such as: large angle gluon radiation, deflected jets, Ĉerenkov gluon radiation, and conical flow generated by hydrodynamic shock-waves. We can discriminate the scenarios wit...

0 Common Features of Particle Multiplicities in Heavy Ion Collisions

Results of a systematic study of fully integrated particle multi-plicities in central Au–Au and Pb–Pb collisions at beam momenta of 1.7A GeV, 11.6A GeV (Au–Au) and 158A GeV (Pb–Pb) using a statistical-thermal model are presented. The close similarity of the colliding systems makes it possible to study heavy ion collisions under definite initial conditions over a range of centre-of-mass energies...
