Anisotropy in High Energy Nucleus - Nucleus Collisions
The predictions of event anisotropy parameters from transport model RQMD are compared with the recent experimental measurements for 158A GeV Pb+Pb collisions. Using the same model, we study the time evolution of event anisotropy at 2A GeV and 158A GeV for several colliding systems. For the first time, both momentum and configuration space information are studied using the Fourier analysis of th...
متن کاملReconstructing azimuthal distributions in nucleus–nucleus collisions
Azimuthal distributions of particles produced in nucleus-nucleus collisions are measured with respect to an estimated reaction plane which, because of finite multiplicity fluctuations, differs in general from the true reaction plane. It follows that the measured distributions do not coincide with the true ones. I propose a general method of reconstructing the Fourier coefficients of the true az...
متن کاملSubthreshold antiproton production in nucleus-nucleus collisions.
Antiproton production from the secondary process pp~ pp is studied for nucleus-nucleus collisions at energies which are below the threshold for its production from the nucleon-nucleon reaction in the free space. In an expanding fireball model, we determine the p abundance from the fusion of pions and find that for collisions at 2. 1 GeV/nucleon the antiproton to negative pion ratio is = 5.5&10 ...
متن کاملStrangeness Dynamics in Relativistic Nucleus-nucleus Collisions *
We investigate hadron production as well as transverse hadron spectra in nucleus-nucleus collisions from 2 A·GeV to 21.3 A·TeV within two independent transport approaches (UrQMD and HSD) that are based on quark, diquark, string and hadronic degrees of freedom. The comparison to experimental data demonstrates that both approaches agree quite well with each other and with the experimental data on...
متن کاملcharm production in relativistic nucleus - nucleus collisions ∗
We calculate excitation functions for open charm mesons in Au + Au reactions from AGS to RHIC energies within the HSD transport approach which is based on string, quark, diquark (q, ¯ q, qq, ¯ q ¯ q) and hadronic degrees of freedom. The open charm cross sections from pN and πN reactions are fitted to results from PYTHIA and scaled in magnitude to the available experimental data. From our dynami...
