论文摘要
我们研究了高温QCD等离子体中介质引起的喷气机的碎片。基于QCD的有效动力学理论，我们研究了喷射淋浴的非平衡演化以及介质中喷气片段的化学平衡。通过包括辐射排放和弹性相互作用，我们的方法从射流能量尺度一直延伸到介质的温度，并包括重要的效果，例如培养基的后座。我们提出了中等片段化的结果，包括软片段的化学和动力学平衡，并讨论了我们结果对喷气淬灭物理学的影响以及重离子碰撞中夸克 - 网状血浆的热化问题。
We investigate the medium induced fragmentation of jets in a high-temperature QCD plasma. Based on an effective kinetic theory of QCD, we study the non-equilibrium evolution of the jet shower and the chemical equilibration of jet fragments in the medium. By including radiative emissions as well as elastic interactions, our approach extends all the way from the jet energy scale to the temperature of the medium and includes important effects such as the recoil of the medium. We present results for the in-medium fragmentation, including chemical and kinetic equilibration of the soft fragments and discuss implications of our result to jet quenching physics and the problem of thermalization of the quark-gluon plasma in heavy ion collisions.
