Description
In the collisions of ultrarelativistic heavy ions the energy of the nuclei is
released in a small volume leading to the creation of a hot and dense nuclear
matter. The study of the particles produced from it gives the information on
the conditions in the early stage of the collision and the evolution of the
system. The PHOBOS experiment provides unique data on the particle production
in the almost full phase space and down to very small transverse momenta.
The talk will present an overview of recent results from the PHOBOS
experiment. The extensive studies of charged particles production are based on
the multiplicity measurements in a very wide pseudorapidity range and reveal
strong short and long range correlations. Their dependence on the collision
centrality for the two colliding systems: Au+Au and Cu+Cu is analyzed. In
addition both the high and very low pT distributions, the particle ratios and
elliptic flow results will be shortly presented.
