论文摘要
在相对论能量的核核碰撞中，产生了一种新的物质，即夸克 - 胶原等离子体（QGP）。该物质和化学冷冻点的相图将与伪themention的伪临界温度有关。保守的电荷波动在使手性相变本质的实验访问权限方面的作用将以与晶格QCD的关系和当前的实验数据进行总结。 QGP可以被描述为一种几乎理想的液体，在流体动力学上膨胀，实验数据允许提取传输参数，例如散装和剪切粘度。 QGP中Parton的能量损失探测了培养基的高部分密度。 Quarkonia和开放式魅力HADRON的作用是探测解浓义和强调的探测，构成了最后一个主题。
In nucleus-nucleus collisions at relativistic energies a new kind of matter is created, the Quark-Gluon Plasma (QGP). The phase diagram of such matter and the chemical freeze-out points will be presented in connection to the pseudo-critical temperature for the chiral cross over transition. The role of conserved charge fluctuations to give experimental access to the nature of the chiral phase transition will be summarized in terms of the relation to lattice QCD and the current experimental data. The QGP can be characterized as a nearly ideal liquid expanding hydrodynamically and the experimental data allow to extract transport parameters such as the bulk and shear viscosities. The energy loss of partons in the QGP probes the high parton density of the medium. The role of quarkonia and open charm hadrons as a probe of deconfinement and hadronization form the final topic.
