论文摘要
许多新颗粒（主要是黑核）是在原子核之间高能碰撞中产生的。描述强子生产过程的最受欢迎的模型是基于共振，字符串或夸克 - 杜松等离子体的创造，演变和衰变。这些模型的有效性是在生动的讨论中，而且似乎缺少这个讨论的共同框架。在这里，我们介绍了高能核碰撞的图，其中指示了实验室控制参数，碰撞能量和核量碰撞核的统治区域的统治域。我们认为，最近的实验结果定位了域之间的边界，这是第一次绘制示例图。最后，我们讨论了对草图之后的实验测量和模型开发的直接含义。
Many new particles, mostly hadrons, are produced in high energy collisions between atomic nuclei. The most popular models describing the hadron production process are based on the creation, evolution and decay of resonances, strings or quark-gluon plasma. The validity of these models is under vivid discussion, and it seems that a common framework for this discussion is missing. Here we introduce the diagram of high energy nuclear collisions, where domains of the dominance of different hadron-production processes in the space of laboratory-controlled parameters, the collision energy and nuclear-mass number of colliding nuclei, are indicated. We argue, the recent experimental results locate boundaries between the domains, allowing for the first time to sketch an example diagram. Finally, we discuss the immediate implications for experimental measurements and model development following the sketch.
