这些讲座对超相对论重离子碰撞物理学中的选定主题进行了现代介绍，阐明了强相互作用的基本理论——量子色动力学。重点是存在于碰撞早期和中期阶段的 QCD 物质的部分形式——彩色玻璃凝聚体、等离子体和夸克-胶子等离子体——以及用于描述它们的有效理论。这些理论为在 RHIC 和/或 LHC 的核-核或氘核-核碰撞中观察到的大量显着现象提供了定性甚至定量的见解，例如粒子产生的抑制和前进速度下的方位角相关性、多重性的能量和中心性依赖性、脊效应、极限碎裂、射流猝灭或双射流不对称性。
These lectures provide a modern introduction to selected topics in the physics of ultrarelativistic heavy ion collisions which shed light on the fundamental theory of strong interactions, the Quantum Chromodynamics. The emphasis is on the partonic forms of QCD matter which exist in the early and intermediate stages of a collision -- the colour glass condensate, the glasma, and the quark-gluon plasma -- and on the effective theories that are used for their description. These theories provide qualitative and even quantitative insight into a wealth of remarkable phenomena observed in nucleus-nucleus or deuteron-nucleus collisions at RHIC and/or the LHC, like the suppression of particle production and of azimuthal correlations at forward rapidities, the energy and centrality dependence of the multiplicities, the ridge effect, the limiting fragmentation, the jet quenching, or the dijet asymmetry.
