摘要：

We present results for final state charged-particle (pseudo-)rapidity distributions in p + (p) over bar /p + p and Pb + Pb/Au + Au at ultra high energies (17.3 GeV <= root S-N N <= 14 TeV) from the Ultra-relativistic Quantum Molecular Dynamics (UrQMD-v2.3) model. In addition, excitation functions of produced charged-particle multiplicities (N-ch) and pseudorapidity spectra are investigated up to CERN Large Hadron Collider energies. Good agreement is observed between UrQMD and measured pseudorapidity distributions of charged particles up to the highest Tevatron and Sp (p) over barS energies.
