Experiment NA61 /SHINE at the CERN SPS:Search for the Critical Point andStudy of the Onset of Deconfinement

该项目的目的是寻找强相互作用物质的临界点，并研究解定义开始的性质。申请人在核-核碰撞史上首次在二维参数空间中进行了全面扫描：碰撞核的大小与相互作用能。研究是在欧洲核子研究中心SPS的NA61/SHINE实验中进行的。申请人是该实验的发起人和发言人，该实验包括三个物理项目，涉及宇宙射线、中微子和重离子物理。NA61/SHINE项目的协同作用以及现有加速器链和探测器的使用，为以非常高效和经济的方式实现该项目雄心勃勃的物理目标提供了独特的机会。所要求的DFG支持将用于实验协调、数据采集、校准、分析以及方法和模型的开发。这个项目有可能有一个重要的发现——对强相互作用物质临界点的实验观察。它保证了精确的测量，这对于理解定义起始的性质至关重要。

The objective of the project is to search for the critical point of strongly interacting matter and to study the properties of the onset of deconfinement. The applicant carries out for the first time in the history of nucleus-nucleus collisions a comprehensive scan in two dimensional parameter space: size of colliding nuclei versus interaction energy. The study is performed within the NA61/SHINE experiment at the CERN SPS.The applicant is the initiator and the spokesperson of this experiment, which comprises three physics programs related to cosmic-ray, neutrino and heavy ion physics. Synergy of the NA61/SHINE programs as well as the use of the existing accelerator chain and detectors offer the unique opportunity to reach the ambitious physics goals of the project in a very efficient and cost effective way.The requested DFG support will be used for the experiment coordination, the data taking, calibration, analysis as well as development of methods and models.The project has a potential for an important discovery - the experimental observation of the critical point of strongly interacting matter. It guarantees precision measurements crucial for the understanding of the properties of the onset of deconfinement.
