SPS和QCD Phase Diagram的颗粒生产

Particle Production at the SPS and the QCD Phase Diagram

Christoph Blume

摘要:

本文综述了CERN-SPS能区粒子产生的最新研究结果。为了收集有关QCD相图性质的信息,对重离子碰撞中的系统尺寸和粒子产生的能量依赖性进行了系统的研究。讨论了净重子分布和奇异产生的结果。许多可观的系统大小的依赖性,可以理解的核心电晕的方法,这有可能使用系统的大小作为控制参数来研究不同领域的相图的影响。综述了近年来寻找临界点的一些尝试,如多重数涨落和反重子/重子比的横向质量依赖性。

英文摘要:

Recent results of particle production in the energy regime of the CERN-SPS are reviewed. In order to collect information on the properties of the QCD phase diagram systematic studies of the system size and the energy dependence of particle production in heavy ion collisions have been performed. Net-baryon distributions and results on strangeness production are discussed. The system size dependence of many observables can be understood in the core-corona approach, which has implications on the possibility to use system size as a control parameter to study different areas of the phase diagram. Recent attempts to search for a critical point, such as multiplicity fluctuations and the transverse mass dependence of anti-baryon/baryon ratios are reviewed.
