[1] The structure of the density discontinuity across the plasmapause is often based on electron and H density profiles with the contribution of heavy ions (He, O etc) neglected. Electron and ion density measurements in this region may differ significantly due to the presence of heavy ions and it is important for the intercomparison of different datasets to understand these differences. Dynamic...

Observations by the PHENIX and STAR collaborations suggest that a strongly coupled quark-gluon plasma is produced in heavy-ion collisions at the Relativistic Heavy Ion Collider (RHIC). After a brief introduction to heavy-ion physics, measurements of heavy-quark production in heavy-ion collisions and the modification of heavy-quark spectra by the QGP are presented. Measurements of the total char...

In heavy ion accelerators the beam line vacuum is effected by lost ions impinging on the beam pipe. Due to ion induced desorption gas is released from the walls into the vacuum. This vacuum degeneration effects the ion beam life time and is a serious luminosity limitation for a heavy ion synchrotron like SIS18. Here we report on a new approach to understand the physics of the ion induced desorp...

Ue discuss in this paper some theoritical informations that one can get from experimental results of heavy ions beams-target interaction in the case of gas and plasma with electronic density 17 18 — 3 ranging between 10 and 10 e.cm We focus on tuo particular points : Corrections to the dominant behavior of stopping pouer and dynamical influence on beam charge state.

Shock heating and particle acceleration processes are some of the most fundamental physical phenomena of plasma physics with countless applications in laboratory physics, space physics, and astrophysics. This study is motivated by previous observations of non-thermal heating of heavy ions in astrophysical shocks (Korreck et al. 2004). Here, we focus on shocks driven by Interplanetary Coronal Ma...

With the acceleration of lead nuclei in the LHC, heavy-ion physics will enter a new energy domain. One of the main novelties introduced by the 30-fold energy-jump from RHIC to the LHC is the abundant heavy-quark production. After discussing a few examples of physics issues that can be addressed using heavy quarks, we present a selection of results on the expected experimental capability of ALIC...

Modifications in the production pattern of heavy quark bound states have long been considered to provide sensitive signatures for the thermal properties of dense matter created in heavy ion collisions. The original concept of Matsui and Satz for quarkonium suppression as signature for deconfinement in heavy ion collisions has been challenged recently through lattice studies of spectral function...

The hot and dense matter generated in heavy-ion collisions may contain domains which are not invariant under P and CP transformations. Moreover, heavy-ion collisions can generate extremely strong magnetic fields as well as electric fields. The interplay between the electromagnetic field and triangle anomaly leads to a number of macroscopic quantum phenomena in these P- and CP-odd domains known ...

To study heavy ion collisions at energies available from the Relativistic Heavy Ion Collider ~RHIC!, we have developed a multiphase transport model that includes both initial partonic and final hadronic interactions. Specifically, the Zhang’s parton cascade ~ZPC! model, which uses as input the parton distribution from the heavy ion jet interaction generator ~HIJING! model, is extended to includ...
