项目摘要

Quantum Chromodynamics or QCD is the currently accepted and well-tested theory which sums up our knowledge, to date, of quarks, which are the fundamental constituents of nuclear matter, and of gluons, the particles responsible for nuclear forces. The collisions of heavy atomic nuclei at the relativistic heavy ion collider (RHIC) in Brookhaven is expected to produce a new state of matter, the so-called quark-gluon plasma, which will provide an important new testing ground for QCD, with extreme conditions for various physical parameters such as pressure and temperature, and thus potentially leading to further elucidation,confirmation or extension of the theory. The expected weakening of interparticle forces under such conditions, the so-called screening effects, will be an important ingredient in the interpretation of data from RHIC.In this project, theoretical investigations of different types of screening effects in the quark-gluon plasma, as well as a number of related questions, will be carried out. The basic mathematical strategy, which is an extension of previously used techniques, will be to relate QCD to suitable theories in lower and higher number of spacetime dimensions, an approach which has provided significant new insights recently. Whereverappropriate, results obtained will be correlated with numerical computer-based analysis of such theories.

量子染色体动力学或QCD是当前接受且经过良好测试的理论，它总结了我们迄今为止的夸克的知识，夸克（Quarks）是核物质的基本成分，以及负责核力量的颗粒的胶体。在布鲁克黑文的相对论重离子碰撞器（RHIC）中，重原子核的碰撞预计将产生一种新的物质状态，即所谓的夸克 - 网状血浆，这将为QCD提供一个重要的新测试，并为诸如压力和温度等各种物理参数，从而进一步质疑，以实现QCD的重要条件，从而进一步质疑，以进一步的理论，或者实现的理论。在这种条件下，颗粒室内力的预期减弱，所谓的筛选效应将是解释RHIC的数据的重要组成部分，该项目对Quark-Gluon等离子体中不同类型的筛选效应的理论研究以及许多相关问题的理论研究。基本的数学策略是先前使用的技术的扩展，将是将QCD与较低和较高数量的时空维度相关联的理论，这种方法最近提供了重要的新见解。无论毫无疑问，获得的结果都将与基于计算机的这些理论的分析相关。
