Comparison of experimental data to the relativistic quantum molecular dynamics model for Si+Au collisions at 14.6A GeV/c.

چکیده
Predictions from the RQMD model are systematically compared to recently published charged hadron distributions of AGS Experiment 802 for central Si+Au collisions at 14.6A GeV/c, taking into account both the experimental trigger condition and acceptance. The main features of the data, including K production, can be understood quantitatively to better than 20% within the framework of the model, although several discrepancies are found, most importantly for the proton spectra.

Features of particle multiplicities and strangeness production in central heavy ion collisions between 1.7A and 158A GeV/c. Abstract A systematic study is performed of fully integrated particle multiplicities in central Au–Au and Pb–Pb collisions at beam momenta of 1.7A GeV/c, 11.6A GeV/c (Au–Au) and 158A GeV/c (Pb–Pb) by using a statistical-thermal model. The close similarity of the colliding ...

Hadron-hadron collisions at high energies are investigated in the Ultrarelativistic-Quantum-Molecular-Dynamics approach. This microscopic transport model describes the phenomenology of hadronic interactions at low and intermediate energies ( √ s < 5 GeV) in terms of interactions between known hadrons and their resonances. At higher energies, √ s > 5 GeV, the excitation of color strings and thei...

A rotationally-symmetrical ellipsoidal flow model is proposed for the relativistic heavy-ion collisions and compared with the 14.6 A GeV/c Si-Al and 10.8 A GeV/c Au-Au collision data. The large stopping in the heavier collision system and heavier produced particles is accounted for by using the ellipsoidal flow picture. The central dip in the proton and deuteron rapidity distributions for Si-Al...
متن کاملHydrodynamic description of ultrarelativistic heavy-ion collisions
Relativistic hydrodynamics has been extensively applied to high energy heavy-ion collisions. We review hydrodynamic calculations for Au+Au collisions at RHIC energies and provide a comprehensive comparison between the model and experimental data. The model provides a very good description of all measured momentum distributions in central and semiperipheral Au+Au collisions, including the moment...
