1. Azimuthal distribution and transverse flow in high-energy nucleus–nucleus collisions

Author

Fu-Hu Liu

Subjects
Azimuth, Out of plane, Physics, Transverse plane, High energy, Flow (mathematics), Distribution (number theory), Elliptic flow, General Physics and Astronomy, Atomic physics, Nuclear Experiment, Computational physics
Abstract

We use a new formula to describe the azimuthal distribution of final-state particles in high-energy nucleus–nucleus collisions. The transverse flow (directed flow and elliptic flow) characteristics are obtained. The corresponding deformed and moving emission source in the momentum space in the transverse plane are given.

Subjects
Nuclear physics, Physics, High energy, General Physics and Astronomy, Particle, Cylinder, Rapidity
Abstract

The rapidity and transverse-momentum distributions of particles produced in central Pb–Pb collisions at high energy are analyzed by the thermalized cylinder model. The calculated results are compared and found to be in agreement with the recent experimental data of the NA49 Collaboration. PACS Nos.: 25.75-q, 24.10Pa

6. Investigation of correlations between conditional moments in nuclear fragmentation at high energy

Subjects

Abstract

The conditional moments of the charge distributions of the projectile fragments in O and S fragmentation are obtained using the partition method. Thus, the logarithmic correlations between the conditional moments can be observed. The electromagnetic dissociations are similar to the correlation behaviour of nuclear reactions. This is illustrated by the correlation behaviour of the oxygen nuclei, which are in agreement with that of the sulphur nuclei. The calculated results correspond to the experimental data of 3.7 and 200 GeV N−1 O–Em and 200 GeV N−1 S–Em interactions.

Abstract

Three isotropic emission fireballs are used to describe the rapidity (or pseudorapidity) and transverse momentum distributions of negatively charged particles produced in nucleus-nucleus collisions at high energy. The calculated results are compared and shown to be in agreement with the experimental data of [SUP16]O-Au, [SUP32]S-S, and [SUP32]S-Ag collisions at 200A GeV. [ABSTRACT FROM AUTHOR]

10. Transverse-energy distribution in proton–nucleus collisions at high energy.

Abstract

Based on the model of nuclear-collision geometry, the independent N–N collision picture and participant contribution picture are used to describe the transverse-energy distribution in p–A collisions at high energy. In the independent N–N collision picture, the energy loss of leading proton in each p–N collision is considered. The calculated results are in agreement with the experimental data of p–Al, p–Cu, and p–U collisions at 200 GeV/c. PACS Nos.: 13.85-t, 13.85Hd, 25.75-qNous décrivons la distribution d'énergie transverse dans les collisions p–A de haute énergie dans le cadre du modèle géométrique des collisions nucléaires et des représentations pour des collisions indépendantes N–N ou à fragments participants. Dans le cas des collisions indépendantes N–N, nous tenons compte de la perte d'énergie du proton dans chaque collision p–N. Les résultats des calculs sont en accord avec les données expérimentales pour les collisions p–Al, p–Cu et p–U à 200 GeV/c.[Traduit par la Rédaction] [ABSTRACT FROM AUTHOR]
