Hadron production in heavy relativistic systems
We investigate particle production in heavy-ion collisions at RHIC energies as function of incident energy, and centrality in a three-sources Relativistic Diffusion Model. Pseudorapidity distributions of produced charged hadrons in Au + Au and Cu + Cu collisions at √ sNN = 19.6 GeV, 62.4 GeV, 130 GeV and 200 GeV show an almost equilibrated midrapidity source that tends to increase in size towar...
متن کاملHadron Production and Phase Changes in Relativistic Heavy Ion Collisions
We study soft hadron production in relativistic heavy ion collisions in a wide range of reaction energy, 4.8GeV < √ sNN < 200GeV, and make predictions about yields of particles using the statistical hadronization model. In fits to experimental data, we obtain both the statistical parameters as well as physical properties of the hadron source. We identify the properties of the fireball at the cr...
متن کاملThermal hadron production in relativistic nuclear collisions
We present the status of the description of hadron production in central nucleus-nucleus collisions within the statistical model . Extending previous studies by inclusion of very high-mass resonances (m> 2 GeV), and the upto-now neglected scalar σ meson leads to an improved description of the data. In particular, the hitherto poorly reproduced energy dependence of theK/π ratio at SPS energies (...
متن کاملHadron Production in Relativistic Nuclear Collisions
Relativistic nucleus-nucleus collisions create a ”fireball” of strongly interacting matter at high energy density. At very high energy this is suggested to be partonic matter, but at lower energy it should consist of yet unknown hadronic, perhaps coherent degrees of freedom. The freeze-out of this high density state to a hadron gas can tell us about properties of fireball matter.
متن کاملPhoton Production and Photon-Hadron Correlations in Relativistic Heavy Ion Collisions
We calculate the production of real photons in relativistic nuclear collisions at RHIC, consistently with the quenching of fast partons. We go beyond one-body observables, and evaluate photon-triggered fragmentation functions, in the kinematical window corresponding to that of experimental measurements.
