摘要：

热致密QCD物质的重要微扰（“硬”）探测之一是介质引起的高能部分子的能量损失，即所谓的“喷流淬灭”，它在冷核物质和QGP中有很大的不同，并导致了一些已经在RHIC数据中定性看到的现象。本文讨论了在现有的相对论重离子碰撞Monte-Carlo模型中，喷流猝灭和其他重要的集体效应，如径向流和椭圆流的加入。本文讨论了HYDJET++模型在RHIC和LHC能区所得到的相应物理观测值的一些问题。

英文摘要：

One of the important perturbative ("hard") probes of hot and dense QCD matter is the medium-induced energy loss of energetic partons, so called "jet quenching", which is predicted to be very different in cold nuclear matter and in QGP, and leads to a number of phenomena which are already seen in the RHIC data on the qualitative level. The inclusion of jet quenching and other important collective effects, such as radial and elliptic flows, in the existing Monte-Carlo models of relativistic heavy ion collisions is discussed. Some issues on the corresponding physical observables at RHIC and LHC energies obtained with HYDJET++ model are presented.
